Abstract
Abstract A radiation image storage panel having a stimulable phosphor layer provided on a substrate with a honeycomb structure constituted of a number of cells partitioned by wall members filled with the stimulable phosphor is prepared by forming the substrate for phosphor layer by casting in a mother mold or etching of the substrate and filling the cells on the substrate with the stimulable phosphor. This radiation image storage panel can give images of markedly improved sharpness.
