英文摘要	An optical module according to the present invention has a stem having an interconnection terminal; an optical device positioned on the stem and electrically connected to the interconnection terminal; a cap fixed onto the stem so as to enclose the optical device within the cap; and a lens for optically coupling the optical device with an optical member positioned outside the cap. As a feature of this optical module, the cap is manufactured with a high degree of precision so that the height of the cap with respect to the stem can be used as a positional reference in the direction of the optical axis of the optical system, which consists of the optical device, the lens, and the optical member extending outside the cap. In addition, the shape of the side wall of the cap is designed so that it can function as a reference for maintaining the coaxiality between the photo detector and the lens. The stem is fixed to the cap at the proper position for a high precision.
