<P>PROBLEM TO BE SOLVED: To provide a power generator having a configuration including a package capable of preventing output reduction. <P>SOLUTION: A power generator 1 has a button type package 40 including: a piezoelectric vibration powered generator 10; a power storage part 20; and charging means 30 that rectifies AC voltage generated by the piezoelectric vibration powered generator 10 and charges the power storage part therewith. The piezoelectric vibration powered generator 10 includes: a supporting part 11, a cantilever 12 which is supported by the supporting part 11 so as to oscillate freely; a weight 13 provided to the front end of the cantilever 12 opposite side to the supporting part 11; and a power generating part 14 provided to the cantilever 12 to generate AC voltage due to the oscillation of the cantilever 12. The package 40 includes: a first case 41 which serves as a positive electrode and a second case 42 which serves as a negative electrode for discharging the power from the power storage part 20; and a communication portion 43 for ensuring communication between the inside and the outside of the package 40. <P>COPYRIGHT: (C)2013,JPO&INPIT |
