Zusammenfassung:	An actuator includes a movable body, a support body having a coil holder, a connection body connected with the movable body and the support body, and a magnetic drive circuit having a coil held by the coil holder and a magnet for vibrating the movable body. The coil holder has a plate part which surrounds at least a part of the coil, and the movable body has a yoke holding the magnet. The plate part has a coil holding part along an outer edge of the coil and a connection body fixing part whose plate thickness is thinner than that of the coil holding part. The connection body includes at least one of a first connection body connecting a first facing part of the yoke with the connection body fixing part and a second connection body connecting a second facing part of the yoke with the connection body fixing part.
