摘要：
A vibration power generator includes a first substrate, a first electrode on the first substrate, a second substrate spaced from and opposite the first substrate, and a second electrode on the second substrate. The first electrode vibrates with respect to the second substrate, and the first electrode and the second electrode include a film retaining electric charges. The vibration generator includes a third electrode with a film retaining electric charges on the first substrate, and a fourth electrode with a film retaining electric charges on the second substrate. The third electrode and the fourth electrode are arranged so that the first substrate is retained in a predetermined position when an external force does not act on the first substrate, while an electrostatic force for returning the first substrate to a predetermined position acts on the first substrate and the first substrate moves with respect to the second substrate.
