PROBLEM TO BE SOLVED: To provide an oscillation power generator capable of stably obtaining high generating power.SOLUTION: An oscillation power generator (1) of the present invention comprises: a substrate (S); a cantilever-style oscillation body (P) having a support end supported by the substrate and a free end in the opposite side of the support end, bending in accordance with input for the substrate; and a piezoelectric element joined to the oscillation body and outputting power in accordance with variation of the oscillation body. The oscillation power generator further comprises: an oscillation weight (W) including a first permanent magnet provided in the free end side of the oscillation body; and an oscillation control body (Cs, Cn) including a second permanent magnet arranged at a distance from the oscillation weight and repelling the first permanent magnet, and controlling oscillations of the oscillation weight. Because the oscillation weight and the oscillation control body repel from each other, the oscillation body repeats stable oscillation without plastic deformation even if a large external force acts on the oscillation weight. Consequently, the oscillation power generator of the present invention stably outputs with high performance of power generation. |
