摘要： A vibration actuator that cooperates with a coil and a magnet to vibrate a movable body with respect to a stationary body, including: the stationary body including the coil and a core around which the coil is wound; a shaft part; and the movable body including the magnet, the movable body being movably supported by the stationary body via the shaft part, wherein the core is disposed along an axial direction of the shaft part, and includes a core-side magnetic pole to be excited by energization to the coil, the magnet includes a magnet-side magnetic pole disposed so as to face the core-side magnetic pole with a gap therebetween, and the vibration actuator further includes a spring part elastically supporting the movable body with respect to the stationary body, linearly movably in the axial direction in a reciprocating manner, and rotationally movably about an axis in a reciprocating manner.
