Abstract
An electrostatic operating apparatus (electrostatic induction generator) includes a first substrate having a first electrode and a second electrode and set in a state where the first electrode and the second electrode are electrically separated from each other at least on the substrate and a second substrate including an electret member, wherein the first substrate and the second substrate are so provided as to be opposed to each other at an interval and so formed as to be movable relatively with each other, and at least one of the first electrode and the second electrode is so formed as to be capacitively coupled with the electret member.
