Abstract
It is an object of the invention to provide a variable capacitor constituted such that, even when an external control voltage is applied, a stable dielectric constant of the dielectric layer can be obtained. A variable capacitor constituted such that a dielectric layer whose dielectric constant is changed by the application of an external voltage is held between an upper electrode layer and a lower electrode layer, wherein a plurality of capacitance-producing regions a, b are connected to each other.
