Abstract: A polymer speaker is configured to include an electrostrictive element having an elastomer or resin dielectric layer and a plurality of electrode layers arranged on the front and back surfaces of the dielectric layer. The electrode layers are formed from a conductive material including a polymer binder and a conductor and having a modulus of elasticity of 100 MPa or less. The spring constant of the electrode layers in the surface direction is smaller than the spring constant of the dielectric layer in the surface direction. The volume resistivity of the electrode layers is 200 Ω·cm or less. The polymer speaker provides a practical sound pressure in a wide frequency region from low frequencies to high frequencies.
