Abstract: A membrane switch in which a first conductive part is formed on a first substrate, a second conductive part is formed on a second substrate, and the substrates are layered via a spacer such that the conductive parts face each other with a space therebetween, and an organic material showing piezoelectricity is filled, or disposed in the space such that an air gap is present, are useful for obtaining an output signal corresponding to an applied pressure.
