接方向は常に一定とすることができる。In assembling the light emitting / receiving module having the above-described configuration, the light emitting / receiving element 1 is sandwiched by the light emitting / receiving element holding first member 2 and the second member 3. Further, the rod lens 6 is held by the rod lens holding member 5, and the rod lens holding member 5 is fitted into the adjusting member 4. The adjusting member 4 is brought into contact with the first holding member 2 that holds the light emitting / receiving element, and is moved in the left-right direction in the drawing to be adjusted so that the central axes of the light receiving / emitting element 1 and the rod lens 6 are aligned with each other. Welding with the adjusting member 4 is performed at the portion marked with ▲. Next, the rod lens holding member 5 was slid with respect to the adjusting member 4 in the vertical direction of the figure so that the distance between the light emitting / receiving element 1 and the rod lens 6 became a predetermined distance, and the axial position was adjusted. After that, the adjustment member 4 and the rod lens holding member 5 are welded at the position of the mark ∘ in the figure at the tip of the tapered portion 7. Since the adjusting member 4 has the tapered portion 7 and welding is applied to the tip end portion thereof, the adjusting member 4 itself can be made thick and the rigidity thereof can be increased. Further, since the first light receiving / emitting element holding member 2 and the adjusting member 4 are joined by welding at the recessed portion 8, as a result of the optimum position adjustment, the first light receiving / emitting element holding member 2 and the adjusting member 4 are joined together. Even if there is a step at the joint, the welding direction can be kept constant as indicated by the ▲ mark in the figure.
