Abstract
Provided is a power generating element and a power generating device capable of using vibration energy not used for power generation in the past. The power generating element includes a displacement member, a fixed member, and an elastic deformation body. An electret material layer is formed on a surface of one of the displacement member and the fixed member. A counter electrode layer opposed to the electret material layer is formed on the other surface. When vibration energy is given to the power generating element, the displacement member is displaced with respect to the fixed member such that an inter-layer distance between the electret material layer and the counter electrode layer fluctuates according to deformation of the elastic deformation body.
