Abstract:
A vibration power generator includes a first substrate, a first electrode disposed on a lower surface of the first substrate and including a film retaining electric charges, a second substrate opposing the lower surface of the first substrate, a second electrode disposed on an upper surface of the second substrate, a third electrode disposed on the upper surface of the first substrate and including a film retaining the electric charges, a third substrate opposing the upper surface of the first substrate, and a fourth electrode disposed on a lower surface of the third substrate and opposing the third electrode. The film of the first electrode has a polarity different from a polarity of the film of the third electrode, and the vibration power generator includes a restoring force generation member giving a restoring force when an external force is not exerted to the first substrate.
