<P>PROBLEM TO BE SOLVED: To provide a vibrating actuator capable of highly efficiently improving the rotating force of a rotor. <P>SOLUTION: The vibrating actuator 100 is provided with: the rotor 160 rotatably arranged around a rotating shaft; a stator 120 abutting on the rotor 160; an electromechanical conversion section 130 formed like a circle, when viewed in a rotating shaft direction and supplied with power to generate the displacement around the rotating shaft for the stator 120, thereby rotating the rotor 160; a base section 150 for sandwiching the electromechanical conversion section 130 together with the stator 120; a wiring board 140, sandwiched between the electromechanical conversion section 130 and the base section 150 and supplying power to the electromechanical conversion section 130. The wiring board 140 has an inner peripheral portion 142, spaced from the inner periphery of the electromechanical conversion section 130 or abutting on the inner periphery; and an outer peripheral portion 144 abutting on the outer peripheral side of the electromechanical conversion section 130, with a force which is larger than that of the inner peripheral portion 142. <P>COPYRIGHT: (C)2009,JPO&INPIT |
