Abstract
Abstract A terminal for a piezoelectric device has a first electrode portion, a second electrode portion folded on the first electrode portion, projections on the first and second electrode portions, and further a vibration absorber between the first and second electrode portions. As the vibration absorber, oil, a non-volatile component of oil, silicone grease, polyamide resin, paper, an anticorrosive, a coating agent, silicone rubber, etc. may be used. Another terminal for a piezoelectric device has a sealant between the first electrode portion and the second electrode portion.
