CAPACITANCE ELEMENT, METHOD FOR MANUFACTURING CAPACITANCE ELEMENT, RESONANCE CIRCUIT, COMMUNICATION SYSTEM, WIRELESS CHARGING SYSTEM, POWER SUPPLY DEVICE, AND ELECTRONIC INSTRUMENT

WIPO Patent Application WO/2012/102190

A1

[Problem] To provide a capacitance element with which an electrostatic capacitance can be accurately ensured, and a variable-capacitance element with which a capacitance variability ratio can be adequately ensured; and also to provide a resonance circuit, a communication system, a wireless charging system, a power supply device, and an electronic instrument in which the capacitance elements are used. [Solution] This capacitance element (variable-capacitance element (1)) is provided with a capacitance element body (2) configured from a dielectric layer (4) and at least one pair of capacitance element electrodes (5a, 5b) that sandwich the dielectric layer (4) and generate a desired electric field on the dielectric layer (4). The capacitance element is also provided with stress controllers (6, 7) for controlling stress generated in the dielectric layer (4) of the capacitance element body (2) and increasing the electrostatic capacitance of the capacitance element body (2).
