PROBLEM TO BE SOLVED: To provide a vibration power generating circuit capable of generating power in various environments.SOLUTION: A vibration power generating element 10 has a stator 14 and a movable element 12, and generates power according to displacement of the movable element 12. A first electrode 20 is provided at the movable element 12. The first electrode 20 and a second electrode 30 are provided separated from each other, and have capacitance formed therebetween. A control unit 40 controls a state of the second electrode 30, controls the Coulomb force between the first electrode 20 and the second electrode 30, and adjusts a resonant frequency of the vibration power generating element 10. |
