Abstract: Provided is a sheet-shape electrostatic sound pressure-electrical signal conversion device that is three-dimensionally deformable and has a low drive voltage. The sound pressure-electrical signal conversion device includes a polymer sheet sandwiched between a pair of electrodes facing each other, the polymer sheet is a dielectric film, at least one of the electrodes includes an insulating flexible substrate having a plurality of through-holes and a plurality of conductive fibers having one end fixed to the flexible substrate with a pressure sensitive adhesive, electrical conduction in an in-plane direction is formed by contact between the conductive fibers, the conductive fibers are vibrated by giving an electrical signal to the pair of electrodes or the conductive fibers are vibrated by receiving sound pressure to cause the pair of electrodes to output an electrical signal.
