In a vibration power generator that generates power by relatively moving an electret and an electrode in a state in which the electret and the electrode oppose each other, a gap between the electret and the electrode is suitably formed. In the vibration power generator in which an electret group and an electrode group are provided in a movable member and a fixed member and vibration power generation is performed by displacement of both of the members in a relative movement direction by an external vibration, the electret group and the electrode group are accommodated in a housing portion. In addition, the vibration power generator includes a plurality of support members that are disposed so as to be slidable on the fixed member, are interposed directly between the fixed member and the movable member so as to define a gap between a fixed member-side power generation element and a movable member-side power generation member, and support the movable member so as to allow relative movement of the movable member with respect to the fixed member. Slide surfaces on which the plurality of support members slide are formed on a common substrate surface of a substrate of the fixed member. |
