description Provided is an actuator having a structure with which stress concentration on an elastic member of the actuator can be reduced in a manufacturing process thereof and breakage of the elastic member can be inhibited. The actuator includes a movable member, an elastic member configured to connect the movable member and a supporting member to each other, and an electrode pair having a comb electrode structure for displacing the movable member in a direction perpendicular to a reflective surface in which all movable comb electrodes extending from the movable member are substantially in parallel with one another, and a portion of the elastic member, which is located at a beginning of extension from the movable member, is substantially in parallel with the movable comb electrodes.
