In an optical disc apparatus, a metallic member forming an optical pickup, such as a bottom cover member of the optical pickup, has a protrusion in an integral form on the portion of the metallic member that is opposed to a plane of a flexible printed-wiring board, and the optical pickup is constructed so that when it comes into contact with an opposed face of the flexible printed-wiring board, the optical pickup brings a front end of the protrusion into contact with the opposed face.
