After adjusting the positional relationship between the stem 5 and the ferrule 1 to which the ferrule 1 is fixed or the outer enclosure 2 to which the ferrule 1 is attached, the stem 5 is
On the other hand, since the outer envelope 2 is fixed by brazing, welding, adhesive, etc., the assembly process is complicated and must be performed with great care. Furthermore, even in the case where the spherical lens 6 is attached to the cylindrical body 7 shown in FIG.
Productivity was extremely low as it was necessary to perform fine positioning and fixing work while the machine was operating. Furthermore, the base body (stem 5) on which the light-emitting light-receiving element 3 is attached and the ferrule are separate bodies, and the outer body 2 and the cylindrical body 7 are required, which increases the overall size and the number of parts. Not only is this accompanied by higher costs, but there is also a strong possibility that reliability will deteriorate.
