PROBLEM TO BE SOLVED: To provide a light receiving module where soldering of a shield case is not necessary after the mounting of the shield case on a circuit board. SOLUTION: A terminal 61 extending on a side panel of the shield case 6 is so arranged as to be formed on the surface of a recess 4 in the side of the circuit board 1, and to contact with or neighbor a conductive pattern 41 connected to a conductive pattern 2 or 3 positioned on the upper or lower surface of the circuit board 1. During the process of mounting the circuits and the shield case 6 on the circuit board 1, solder infiltrates into the gap between the terminal 61 and the recess 4 for the formation of a solder fillet in the gap owing to capillarity working in the gap. As the result, the terminal 61 of the shield case 6 is connected to the conductive pattern 41. COPYRIGHT: (C)2005,JPO&NCIPI
