The optical element holder is provided with three holding portions which abut and engage the peripheral side surface of the optical element at first, second and third positions, respectively. One of the holding portions is movable and can be moved to and away from the peripheral side surface of the optical element, thereby securing the optical element in the optical element holder and releasing the optical element from the optical element holder, respectively.
