摘要： A power generating element according to the present invention includes a pedestal formed in a frame shape in plan view, a vibrating body provided inside the pedestal, at least three first bridge supporting portions, each of the first bridge supporting portions extending along a first extending axis and configured to arrange the vibrating body to be supported on a pedestal, and a charge generating element. The first extending axes of a pair of the first bridge supporting portions adjacent to each other form a predetermined angle in a circumferential direction with the vibrating body defined as a center in plan view. At least one first electrode layer of the charge generating element is arranged on each of the first bridge supporting portions.
