In an optical pickup device, an upper plate portion, leg portions and a support shaft are provided in a base member so as to be disposed above a lens holder. A mechanism for adjusting the tilt angle of an objective lens is constituted by lower end surfaces formed out the curved surfaces of the leg portions, and reception surfaces formed out of the valley-like surfaces of an optical chassis. An electromagnetic drive mechanism for the lens holder includes the leg portions, magnets, and coils of the lens holder.
