Abstract
An electrostatic induction type power generation element is capable of increasing the amount of generated power while suppressing a parasitic capacitance between electrodes between which induced electromotive force is generated. An electrostatic induction type power generation element in one embodiment includes: substrates which are opposed to each other and which move relative to each other in a direction parallel to the opposing surfaces of the substrates; a charge retaining unit and conductors which are respectively formed on the opposing surfaces of the substrates; and a substance which is interposed between the substrates opposed to each other and between the charge retaining unit and the conductors, and which has an anisotropic dielectric constant in which a relative dielectric constant in the direction parallel to the opposing surfaces is higher than a relative dielectric constant in a direction orthogonal to the opposing surfaces.
