Abstract
Power generated by a vibration power generator utilizing an electret is efficiently supplied to a power supply load. A vibration power generator includes a first substrate and a second substrate configured to be moved relative to each other by external vibration while remaining opposite each other, a group of a plurality of electrets arranged in the relative movement direction on one surface side of the first substrate, and a group of electrodes arranged in the relative movement direction on a surface side of the second substrate opposite to the group of electrets, and including a first current collecting electrode and a second current collecting electrode. A power supply load to which power generated by the external vibration is supplied and which has an impedance lower than an internal impedance of the vibration power generator is electrically connected to each of the first and second current collecting electrodes.
