Disclosed is an optical pickup device which is small, light, and thin and which is equipped with a tilt adjusting mechanism. A lens holding body holding an objective lens and a support body supporting the lens holding body so as to allow the lens holding body to move in the focusing direction and/or the tracking direction of the objective lens, are supported at two support points on a support body mounting surface of an optical base so as to be rotatable around an axis extending in a tangential direction of an optical disk.
