Abstract
A piezoelectric power generating device includes a power generating element and a package member. The power generating element includes a plate-like piezoelectric element and a metal plate. The piezoelectric element has a pair of principal surfaces opposite each other. The metal plate is bonded to one of the principal surfaces of the piezoelectric element. The package member has a supporting part and a restricting part. The supporting part supports an end of the power generating element in a cantilevered manner. The restricting part is disposed opposite the piezoelectric element with the metal plate interposed therebetween. The restricting part restricts displacement of the power generating element toward the outside of the metal plate.
