摘要： PROBLEM TO BE SOLVED: To provide a piezoelectric generator having high efficiency which is used for multipurposes by making its structure simple and small. SOLUTION: A piezoelectric ceramic body has a structure jointing a metal plate to a piezoelectric ceramic element, and the piezoelectric generator makes its power generation possible by operating a colliding load to the piezoelectric ceramic element or the metal plate. Warp deformation of the metal plate is balanced with the warp deformation of the piezoelectric ceramic element by adjusting the thickness of the metal plate. The center of vibration in the state which the piezoelectric ceramic element and the metal plate are jointed is located at the boundary of the joint of the piezoelectric ceramic element and the metal plate.
