Abstract: An electrostatic speaker is constituted of a vibrator, conductive cloths, and elastic members, which are laminated together and woven together using strings. Since all the constituent elements are restrained in positioning by strings, the overall structure thereof is not substantially changed even when the electrostatic speaker is deformed in shape by bending or curving, wherein it is possible to secure the prescribed positional relationship between the constituent elements, which are not deviated in positioning. It is possible to introduce a sheet composed of a thermoplastic resin, which holds the vibrator and elastic members therein. The conductive cloths can be replaced with film electrodes, each of which is formed such that a conductive polymer layer is formed on a base film composed of a thermoplastic resin.
