An optical pick-up adapted to have ability to conduct a control so as to tilt a lens holder (2), including a supporting block (3) for movably supporting the lens holder in the focus direction and in the tracking direction, a supporting member (4) including a pair of leg pieces (41), (41) for supporting and allowing the supporting block to be tilted by fixing front end sides of these leg pieces onto a base (16), the leg pieces being arranged such that spacing between the leg pieces increases as a distance from a side at which the supporting block is supported increases toward the front end side, and a drive mechanism (5) for applying a drive force to the supporting block so as to tilt the supporting block by changing a shape of the pair of leg pieces, whereby tilting the lens holder which is supported by the supporting block.
