摘要：
An objective lens driving device includes: a movable section 8 for collecting light of a light source onto an optical disk 2; and a driving section for driving the movable section 8 (i) in a direction of a light axis of an objective lens 1 which direction is orthogonal to a storage surface of the optical disk 2 and (ii) in an in-plane direction orthogonal to the light axis, wherein the movable section 8 includes a protruding portion 4 which protrudes in a direction orthogonal to the direction of the light axis of the objective lens 1, and there is provided a stopper section 16 for restricting a movable range of the movable section 8 by coming into contact with the protruding portion 4 when the movable section 8 moves.
