PROBLEM TO BE SOLVED: To improve the power generation efficiency of an electrostatic induction type power generation device which converts kinetic energy into power-generating energy by utilizing an electret. SOLUTION: An outer periphery support part 21 of a counter electrode part 20, having a configuration as a counter electrode 22, is movably supported on the outer periphery support part 21 by using a beam 23 is jointed via an insulating spacer 2, to a peripheral edge part of an electret electrode part 10 in which an electret electrode 12 is provided on a conductor 11. A lid member 3 of insulating material is jointed to the outer peripheral support part 21 of the counter electrode part 20, to form a vacuum space part 4, and the electret electrode 12 and the counter electrode 22 are arranged to face each other inside the vacuum space part 4.
