Abstract
A vibration power generator comprises: a fixed substrate; a vibrating body having a surface opposed to the fixed substrate, the vibrating body being vibratable to the fixed substrate; electret electrodes aligned in a vibration direction on one of the surface of the fixed substrate and the surface of the vibrating body; and first fixed electrodes and second fixed electrodes alternately aligned in the vibration direction on the other thereof, wherein when the vibrating body is at a resting position, each of the electret electrodes overlaps with both electrodes of a corresponding fixed electrode pair, the corresponding fixed electrode pair being one of the first fixed electrodes and one of the second fixed electrodes that are opposed to the electret electrode, and when the vibrating body is not at a resting position, each of the electret electrodes always overlaps with at least one electrode of the corresponding fixed electrode pair.
