PROBLEM TO BE SOLVED: To provide a lamination type power generator capable of achieving high power generation efficiency and high reliability by a simple structure.SOLUTION: A lamination type power generator 10 is configured by laminating a plurality of vibration power generators 1. Each of support members 2 is interposed between the vibration power generators 1. The support member 2 is formed and joined on the approximately whole surfaces of the vibration power generators 1. It is preferable that the support members 2 formed on the front and rear sides of respective vibration power generators 1 are elastic bodies. Each vibration power generator 1 is arranged so that an electret dielectric 3 is held between a pair of electrodes 5a, 5b. One electrode 5a and the electret dielectric 3 are joined with each other over the approximately whole surfaces. The other electrode 5b and the electret dielectric 3 are joined with each other through junction parts 7 which are partially formed with gaps between the electrode 5b and the electret dielectric 3 and a gap (air gap) corresponding to the thickness of the junction part 7 is formed between the electrode 5b and the electret dielectric 3 except portions joined with each other through the junction parts 7. |
