description An optical pickup device includes: a carriage moveably supported on an upper surface of a mount base and holding a light source, a light condensing member and optical components guiding the laser light from the light source to the light condensing member; a wiring member connected to the light source to supply electric power thereto; and a protection cover covering the upper surface of the mount base and a part of the wiring member and is provided with an opening through which the laser light passing through the light condensing member is irradiated onto the optical disk. The light source, light condensing member and optical components are located within a region obtained by projecting the opening in a direction perpendicular to a disk surface of the optical disk, and at least one of the light source, light condensing member and optical components protrudes into the opening in the protection cover.
