Abstract
Abstract A conductive structure in which conductive fibers a 1 are sticked to the substrate B by melting thermally fusible fibers a 2 entangling with said conductive fibers a 1 . This structure is manufactured by sticking conductive fibers a 1 to the surface of the substrate B to which the cloth-like material A containing conductive fibers a 1 and thermally fusible fibers a 2 is sticked under pressure at a temperature not lower than a melting point of said thermally fusible fibers a 2 .

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
122 words
A method of manufacturing a conductive structure which comprises: subjecting a non-woven fabric containing 0.01 to 99% by weight of copper-adsorption fibers having a cyano radical and reduced after being subjected to adsorption of copper ion thereto and 99.99 to 1% by weight of thermally fusible fibers and a thermoplastic resin molded non-fibrous material in the form of sheet, film or board to fusion bonding under pressure at a temperature exceeding a melting point of said thermally fusible fibers so that said thermally fusible fibers are melting to form a layer translucent enough to allow the non-fibrous material to be perceived therethrough, said copper-adsorption fibers maintaining initial appearance thereof and being fused to the surface of said thermoplastic resin molded non-fibrous material.
Claim 2
Independent Claim
122 words
A method of manufacturing a conductive structure which comprises: subjecting a non-woven fabric containing 0.01 to 99% by weight of copper-adsorption fibers having a cyano radical and reduced after being subjected to adsorption of copper ion thereto and 99.99 to 1% by weight of thermally fusible fibers and a thermoplastic resin molded non-fibrous material in the form of sheet, film or board to fusion bonding under pressure at a temperature exceeding a melting point of said thermally fusible fibers so that said thermally fusible fibers are melting to form a layer translucent enough to allow the non-fibrous material to be perceived therethrough, said copper-adsorption fibers maintaining initial appearance thereof and being fused to the surface of said thermoplastic resin molded non-fibrous material.
Claim 3
Dependent Claim
65 words
A method of manufacturing a conductive structure as set forth in claim 1, wherein there is provided a structure in which copper-adsorption fibers are fused to the surface of the thermoplastic resin molded non-fibrous material thereof by overlaying the non-woven fabric on the thermoplastic resin molded non-fibrous material or fusing both members together and then pressing them by means of a heating body for heat-fusing.
Claim 4
Dependent Claim
56 words
A method of manufacturing a conductive structure as set forth in claim 1, wherein there is provided a structure in which copper-adsorption fibers are fused to the surface of the thermoplastic resin molded non-fibrous material there of by applying extrusion coating to the non-woven fabric with molten resin for forming the thermoplastic resin molded non-fibrous material.
Claim 5
Dependent Claim
66 words
A method of manufacturing a conductive structure as set forth in claim 1, wherein there is provided a structure in which copper-adsorption fibers are fused to the surface of the thermoplastic resin molded non-fibrous material thereof by inserting the non-woven fabric into a mold and then injecting molten resin into the mold for forming the thermoplastic resin molded non-fibrous material according to an injection molding method.
Claim 6
Dependent Claim
72 words
A method of manufacturing a conductive structure as set forth in claim 1, wherein there is provided a structure in which copper-adsorption fibers are fused to the surface of the thermoplastic resin molded non-fibrous material thereof by inserting the non-woven fabric into a mold and then pressing and fusing a heated and softened thermoplastic resin molded non-fibrous material to the non-woven fabric according to a vacuum molding or deep drawing molding method.
