An optical pickup device includes an optical pickup base having an opening through which reflected light from an optical disc passes to the outside, a light-receiving element shaped like a substantially rectangular plate and configured to convert the reflected light passing through the opening into an electrical signal, and a holder configured to hold the light-receiving element while surrounding a side face of the light-receiving element and attached in contact with an outer wall around the opening so that a light-receiving surface of the light-receiving element faces the opening. The optical pickup base and the holder are formed so that the holder can slide along a first axis parallel to the outer wall, and the holder is formed so that the light-receiving element can slide along a second axis perpendicular to the outer wall and a third axis orthogonal to the first axis and parallel to the outer wall.
