Abstract

A DC to DC converter is provided with a first element for raising a voltage from a voltage-generating source based on capacitance-varying operation effected by an actuator section. The first element comprises a capacitance-forming component and the actuator section. The actuator section includes an operating section, a vibrating section for supporting the operating section, and a fixed section for vibratingly supporting the vibrating section. The operating section includes a shape-retaining layer, an upper electrode, and a lower electrode. The capacitance-forming component includes the upper electrode of the actuator section, a dielectric member formed on the upper electrode, and an electrode section connected to a current supply line.
