Abstract
A thin film layer formed of a material having good wetting properties with respect to solder is laid on a joining surface of a second substrate, and at the same time, a thin film layer formed of Au is laid on a joining surface excluding concave grooves of a first substrate, and optical fibers are placed in the concave grooves of said first substrate, and then urged by the second substrate from the upper side thereof to cause the thin film layer on the first substrate to be plastically deformed and joined by a solder. The solder allows the optical fibers to be urged against the concave grooves of the first substrate, and at the same time, the thin film layer which is formed of Au and protruded to the concave groove side allows a change in the volume of the solder and a dislocation of the optical fibers to be prevented, and the optical fibers to be positioned fixedly at a high accuracy in the concave grooves.
