ピツクアツプ。 A mirror that reflects laser light to obtain reflected light;
a shaft whose central axis is parallel to the optical axis of the reflected light; an objective lens disposed close to the shaft so that the central axis substantially coincides with the reflected optical axis; and a housing that holds the mirror and the shaft. In the optical pick-up, a part of the casing is raised to form a slope, the mirror is shaped like a plate glass and adhered to the slope, and the optical pickup is arranged so that the optical axis of the reflected light almost coincides with the central axis of the objective lens. An optical pickup characterized in that the slope of the slope is determined, and the end face of the mirror on the shaft side is shaped to be substantially parallel to the shaft.
