Abstract
An actuator may include a movable body; a support body; a connecting body; and a magnetic driving circuit. The magnetic driving circuit may include an air-core coil provided in a first member, and a first permanent magnet provided in a second member so as to face the coil on a first side in a first direction. The magnetic driving circuit may cause the movable body to vibrate with respect to the support body in a second direction which intersects with the first direction. The first member may include a coil holder comprising a plate part in which a coil placement hole is formed, a first plate that overlaps the coil placement hole and the plate part, and an adhesive layer. The coil may face the first permanent magnet via the first plate.
