Abstract

See full text

To provide a capacitive device capable of accurately securing a capacitance value, a variable capacitive device capable of sufficiently securing a capacity variability rate, and a resonance circuit that uses the capacitive devices. A capacitive device includes a capacitive device body constituted of a dielectric layer and at least a pair of capacitive device electrodes that sandwich the dielectric layer and cause a desired electric field in the dielectric layer; and stress adjustment portions to adjust a stress caused in the dielectric layer of the capacitive device body.
