An actuator may include a movable body; a support body; a connecting body arranged where the movable body and the support body face each other to contact both of the movable body and the support body; and a magnetic drive circuit. The magnetic drive circuit may include an air-core coil provided on a first-side member among the movable body and the support body; and a permanent magnet provided on a second-side member among the movable body and the support body to face the coil in a first direction, the magnetic drive circuit being configured to vibrate the movable body with respect to the support body in a second direction crossing the first direction. In the first-side member, the coil may be fixed by an adhesive to a surface of a plate-shaped coil holder on a first side in the first direction while an air-cores is directed in the first direction.
