Abstract
An optical pickup includes an objective lens which converges light on an optical disc, a lens holder to which the objective lens is attached, a focusing coil and a tracking coil wound around the lens holder, magnets arranged to face two side faces of the lens holder parallel to a radial direction of the optical disc, supporting members which support the lens holder, and supporting member fixation parts provided on two side faces of the lens holder orthogonal to the radial direction of the optical disc. The focusing coil is wound on parts of the lens holder on both sides of the lens holder in regard to the radial direction of the optical disc so that each portion of the focusing coil on each side is wound around a winding central axis extending in a direction parallel to the optical axis of the objective lens.
