The tape-like double-sided adhesive sheet 1 is punched out using a punching die 2 designed to punch out a desired shape, and the adhesive sheet 1 is cut out as shown in FIG. 1(b). form.

Peel off the anti-adhesion sheet. In this state, the adhesive sheet 11 is likely to generate dust, so the adhesive sheet 1. seaweed(
The surface of the resin adhesive is smoothed by heating to such an extent that the adhesive does not change its shape or harden due to heat, thereby preventing the adhesive from generating dust. Next, a double-sided adhesive sheet that prevents dust generation 1. is placed in alignment with the edge frame-like surface 41 formed on the upper surface of the light-receiving cable 4, and the transparent glass cap 3 is placed thereon.

Unlike the conventional method where adhesive is applied to either the cap or the photodetector surface, the adhesive does not adhere to unnecessary parts, and it can be sealed by combining them individually, so that they can be sealed against each other. It is possible to seal with high cleanliness because the influence of dirt caused by foreign matter can be eliminated.
