PURPOSE:To obviate the generation of axial misalignment and to allow the exact butting of the front end faces of respective pairs of fibers by fixing the butt surfaces of the fibers inserted into the holes of a capillary with a 1st resin and fixing a cap body and a substrate with a 2nd resin layer. CONSTITUTION:A UV curing resin having nearly the same refractive index as the refractive index of the cores of the fibers 14a, 14b is injected into grooves 8 of the capillary 2. The front ends of the fibers 14a, 14b are then respectively separately inserted into the holes 9a, 9b of the capillary 2 and the front end faces are butted against each other. The coated tape optical fibers 13a, 13b are then fixed by, for example, fixing jigs, etc., not shown in Fig. The capillary 2 is irradiated with UV rays to cure the UV curing resin, by which the 1st UV curing resin layer is formed. The UV curing resin 19 is injected over the entire front surface of the substrate 1 and the cap body 10 is put on the substrate 1. The front surface of the substrate 1 is irradiated with the UV rays through the cap body 10 to cure the UV curing resin 19, by which the 2nd UV curing resin layer is formed. Such connecting device is small in connection loss, is stable in performance and is excellent in environmental resistance. |
