PIEZOELECTRIC GENERATOR AND METHOD OF MANUFACTURING THE SAME

To provide a piezoelectric generator which can be manufactured simply in few steps and also capable of promoting miniaturization and high performance of the entire device, and a method of manufacturing the same.SOLUTION: A piezoelectric generator 10 according to the present invention includes: a body 11 which has flexibility and in which electrodes 24 and 27 are brought into contact with respective piezoelectric bodies 17 and 20 made of a piezoelectric material; and a laminate 12 coating the entire outer surface of the body 11 from the outside. In the piezoelectric generator, an electromotive force is generated by stress acting on the body 11. The body 11 is configured as a laminate in which a plurality of members including the piezoelectric bodies 17 and 20 and the electrode 24 and 27 are laminated, and includes a gap 29 which restricts partial lifting of an interlayer junction site thereby to improve adhesion of the interlayer junction site.SELECTED DRAWING: Figure 2 【課題】少ない工程で簡単に製造可能で、且つ、装置全体の小型化や高性能化を促進できる圧電型発電装置及びその製造方法を提供すること。【解決手段】本発明に係る圧電型発電装置１０は、可撓性を有するとともに、圧電材料からなる圧電体１７，２０に電極２４，２７を接触させてなる本体部１１と、本体部１１の外面全体を外側から被覆するラミネート部１２とを備えており、本体部１１に作用する応力により起電力を発生させる。本体部１１は、圧電体１７，２０及び電極２４，２７を含む複数の部材を積層した積層体として構成されるとともに、層間接合部位の部分的な浮きを規制し、当該層間接合部位の密着性を向上させる空隙部２９を備えている。【選択図】 図２
