Abstract
A vibration energy harvester includes: a first electrode; and a second electrode that can be displaced relative to the first electrode along a predetermined vibrating direction. At least either of a surface of the first electrode and a surface of the second electrode facing opposite each other is electrically charged. Power is generated as the second electrode becomes displaced causing a change in electrostatic capacitance between the first electrode and the second electrode. A range having included therein at least a vibrational center of the second electrode, over which the electrostatic capacitance remains unchanged even as the second electrode is displaced, is set.
