<P>PROBLEM TO BE SOLVED: To provide a communication light detector by which existence/nonexistence of using state of optical transmission lines is visibly and easily determined by using invisible light propagating in the optical transmission lines. Ž<P>SOLUTION: The communication light detector 1, by which end parts of the optical transmission lines composed of optical fibers 2a and 2b are connected via a sleeve 6, and the existence/nonexistence of the communication light in the optical transmission lines is detected at the connection part, comprises: an optical detection connector 7 which is provided at the connection part in the sleeve 6, connects the end parts of the optical transmission lines, and has a core part 9 of which the outer diameter is different from that of the core 3 of the optical transmission lines; and an optical detection part which is provided above the optical detection connector 7 and detects the leaked light of the communication light leaked via the optical detection connector 7.
