A DC to DC converter (10) is provided with a first element (16) for raising a voltage (Vin) from a voltage-generating source (14) based on capacitance-varying operation effected by an actuator section (32). The first element (16) comprises a capacitance-forming component (30) and the actuator section (32). The actuator section (32) includes an operating section (36), a vibrating section (38) for supporting the operating section (36), and a fixed section (44) for vibratingly supporting the vibrating section (38). The operating section (36) includes a shape-retaining layer (46), an upper electrode (48a), and a lower electrode (48b). The capacitance-forming component (30) includes the upper electrode (48a) of the actuator section (32), a dielectric member (50) formed on the upper electrode (48a), and an electrode section (52) connected to a current supply line (12). <IMAGE> |
