PROBLEM TO BE SOLVED: To provide a communication light detection module which has a multicore connector and allows for checking communication status of a plurality of optical transmission lines, and to provide a structure for detecting communication light.SOLUTION: A communication light detection module 100 includes a plurality of optical transmission lines 101 and a multicore connector 102 to which the plurality of optical transmission lines 101 are inserted in parallel and fixed therein and which has an adhesive filling section 104 that exposes the plurality of optical transmission lines 101 and is filled with adhesive 103 to fix each of the plurality of optical transmission lines 101. Each of the plurality of optical transmission lines 101 has a light extraction section 107 for extracting a portion of communication light 105 as leakage light 106, and is inserted to the multicore connector 102 and fixed therein such that the light extraction section 107 is positioned in the adhesive filling section 104. |
