A reflecting apparatus that includes a mirror having an axis. A holding unit holds the mirror via an elastic member. A first actuator positions the mirror by driving the holding unit. A second actuator deforms the mirror and includes a magnetic member attached to the mirror, and an electromagnet arranged to oppose the magnetic member. The electromagnet generates an attraction force between the magnetic member and the electromagnet. A base supports the electromagnet, and a spring interposed between the base and the mirror applies a force between the magnetic member and the electromagnet in a direction opposite to that of the attraction force. A rigidity of the spring in a direction parallel to the axis is less than that of the elastic member in the direction parallel to the axis.
