摘要： 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 including a plate part through 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 include a first holding portion that engages the first plate to hold the first plate.

摘要： An optical unit is provided which enables performing shake correction of a moving element in the optical axis direction and the direction around the optical axis with a simple configuration and which takes into account ease of assembly. Specifically, this optical unit is provided with: a moving element (14) which is provided with an optical module; a static element (16); a rolling support mechanism (20) which supports the moving element with respect to the static element rotatably about the optical axis of the optical module; and a rolling drive mechanism (18) which rotates the moving element about the optical axis. The rolling support mechanism is provided with elastic members (36) which are arranged in multiple locations around the optical axis in positions between the moving element and the static element; the elastic members (36) are provided with one end part (36a), with an other end part (36b), and with a first elastic part (36c) and a second elastic part (36d) that are arranged between the one end part and the other end part. The first elastic part extends along the direction of the optical axis and generates an elastic force around the direction of the optical axis; the second elastic part extends from the first elastic part in a direction that crosses the optical axis, and generates an elastic force in the direction of the optical axis.
