An optical control device is provided that controls an angle of a reflecting member. The optical control device includes a holding portion, an actuator, an angle detection unit, and a control unit. The angle detection unit is provided at a position outside an outer shape of the actuator in an actuator holder on which the actuator is placed, and detects a rotation angle of the reflecting member. The control unit drives the actuator based on the angle detected by the angle detection unit, and controls the rotation angle of the reflecting member.
