Electrostatic induction conversion device
First Claim
1. An electrostatic induction conversion device for converting between electric energy and kinetic energy, comprising:
- an electret moving relatively to a conductor and made of a polymer which is obtained by cyclopolymerizing a fluorine-containing monomer having two or more polymerizable double bonds and has a fluorine-containing aliphatic cyclic structure in a main chain.

Abstract
There is provided an electrostatic induction conversion device which is small, has high conversion efficiency between electric energy and kinetic energy, and can prevent degradation of an electret. The electret is formed by injecting an electric charge into the vicinity of the surface of an insulating material, is disposed between two conductors, and is constructed so that it moves relatively to at least one of the conductors opposite to the electret and converts between electric energy and kinetic energy. As the insulating material forming the electret, it is preferable to use a polymer having a fluorine-containing aliphatic cyclic structure.
