Abstract
A vibration power generation device including a multiple-degree-of-freedom vibration system comprising a first vibration system and a second vibration system, wherein a natural frequency of the first vibration system is different from a natural frequency of the second vibration system. A first mass member of the first vibration system has a hollow structure including a housing space inside, where the second vibration system is housed. A power generating element is mounted on a plate spring of the second vibration system. A support part projects within the housing space, and one end side of the plate spring is attached to the support part and supported within the housing space at a position inward from a peripheral wall of the first mass member. A second mass member of the second vibration system is attached to another end side of the plate spring.
