[Problems to be Solved by the Invention] As described above, in the conventional light emitting and receiving device, the light emitting and receiving element 3 is used.
And the fiber F attached to the ferrule 1 must be precisely aligned and fixed. This work is performed by actually operating the light emitting and receiving element 3, and the ferrule 1 to which the optical fiber F is fixed or the ferrule 1 is fixed. After adjusting the positional relationship between the outer enclosure 2 having the attached and the stem 5, the outer enclosure 2 is brazed to the stem 5, fixed by welding, adhesive, etc., so that the assembly process is complicated, and It had to be done with great care. Moreover, even in the case where the spherical lens 6 is attached to the tubular body 7 shown in FIG. 4,
Since the focus, the optical axis, etc. of the spherical lens 6 have to be finely adjusted and fixed under the operation of the light emitting and receiving element 3 as described above, the productivity is extremely poor. Further, since the base body (stem 5) on which the light emitting and receiving element 3 is mounted and the ferrule are separate bodies, and the outer enclosure 2 and the tubular body 7 are required, the overall shape becomes large and the number of parts increases. Not only is there a high cost due to, but there is a great risk that it will cause a decrease in reliability.
