摘要：
An actuator, includes: a movable plate; a supporter to support the movable plate; a pair of linking portions to link the movable plate and the supporter so as to allow the movable plate to rotate relative to the supporter; and a piezoelectric element to rotate the movable plate. The piezoelectric element elongated and contracted by an energization twists the pair of linking portions to rotate the movable plate, and each of the pair of the linking portions includes an axial member extending from the movable plate and a returned portion that links the axial member and the supporter and is formed so as to return to a side adjacent to the movable plate.
