An optical member driving device includes an optical member that light is incident on; and a plurality of actuators that shift different portions of an outer peripheral edge of the optical member in a traveling direction of the light immediately before the light is incidence. Each of the plurality of actuators includes an arm that rotates about a rotation center line extending in a direction perpendicular to the traveling direction and supports the optical member at a first end of the arm, a conductor that is provided at a second end of the arm and extends in a direction from the second end toward the first end, the conductor being where a current flows, and a magnet pair that is provided to sandwich the second end of the arm at an interval and generates a magnetic field in a direction intersecting with a direction where the conductor extends.
