Abstract
Provided is a power generation device having a dielectric body and an electret, where power is generated by varying the distance between the dielectric body and the electret. A first electrode is connected to the electret on a side not facing the dielectric body. The first electrode is connected to a grounding terminal via a load. A second electrode may be connected to the dielectric body on a side not facing the electret. The second electrode may be directly connected to the grounding terminal.
