<P>PROBLEM TO BE SOLVED: To provide a piezoelectric power generation unit which is high in reliability, has fewer connection points of wiring than a conventional one, and besides is low in height. <P>SOLUTION: In this cantilever support type of piezoelectric power generation unit, one end of a piezoelectric bimorph 20 is constituted by sandwiching an elastic plate 3 as an intermediate layer between two piezoelectric ceramic plates 1 and 2 and sticking them together and is fixed to a fixing part for support to perform power generation by an external force added to the piezoelectric bimorph 20. A block 5 for fixation is fixed to one end of the elastic plate 3, and the block 5 is screwed to a glass epoxy circuit board 22 being the fixing part. A land 6 plated with solder is created on the glass epoxy circuit board 22 under the block 5, and an electric connection can be made by fixation of the piezoelectric power generation unit 20. <P>COPYRIGHT: (C)2011,JPO&INPIT |
