Abstract
An electric power generator capable of using external vibrations in various directions to generate power. A fixed substrate having a surface with a plurality of electret electrodes and a movable substrate having a surface with a movable electrode are spaced from each other. The fixed substrate is fixed in the electric power generator. Spring driving bodies support the movable substrate so that the movable substrate elastically moves in any direction within an XY plane when receiving external vibrations.
