An optical pick-up device includes a lens that focuses light onto a recording medium, a lens holder that holds the lens, a suspension holder that supports the lens holder disposed opposite a distal end of the lens holder, a frame formed so as to be disposed opposite both lateral surfaces of the lens holder and the distal end of the lens holder, the frame supporting the suspension holder, a plurality of elastic supports that movably support the lens holder, a distal end of the elastic supports mounted on the suspension holder, and an actuator that drives the lens holder, wherein a plurality of projections is provided on at least one of the lens holder, the frame and the suspension holder, the projections acting as stoppers that restrict a rotation of the lens holder so as to prevent excessive deformation of the elastic supports.
