Piezoelectric power generator

摘要

A piezoelectric power generator having a first elastic body which deforms along a first direction when subject to a stress, and a power-generating element. The power-generating element includes a second elastic body and a piezoelectric element. The second elastic body includes a fixing portion and an abutting portion. The fixing portion is fixed to the first elastic body. The abutting portion is arranged on one side in a first direction with respect to the fixing portion. The abutting portion abuts against the first elastic body, but is not fixed to the first elastic body. At least one of the first elastic body and the second elastic body is provided with a slippage suppression mechanism that suppresses slipping of the abutting portion with respect to the first elastic body when the first elastic body is deformed.
