Abstract
An optical pickup device with an objective lens movable in two directions comprises a supporting member having a plate-shaped supporting portion mounted with a bobbin to which an objective lens is attached. The bobbin is mounted so that it can be freely moved in a first direction parallel to the optical axis of the objective lens and/or in a second direction perpendicular to the optical axis of the objective lens, and an electromagnetic driving device drives the bobbin in the first and second directions. The supporting member is unitarily formed with four arms supporting the bobbin at one end and a coupling portion for connecting the four arms at the other end.
