PROBLEM TO BE SOLVED: To provide a power generator which is attached to a vibrating body such as a machine, generates power by utilizing vibrations, and achieves stable output.SOLUTION: A vibration power generator includes: a housing 10; a vibration part 14 including a magnetostrictive member 12; magnetic field application members 16a, 16b which apply magnetic fields to the magnetostrictive member 12; and a coil 18 wound around the magnetostrictive member 12. The vibration part 14 which is supported by a support part 20 so as to vibrate has a vibration amplitude suppression member 24 which is disposed so as to contact with the vibration part 14 and suppresses the vibration amplitude of the vibration part 14. |
