発生させることがある。The conventional water leakage detection cable having the above structure has the following problems. First,
Since the water-permeable insulating tape 1 is provided with the water-permeable port 5 for exposing the conductor 3, it cannot be used to detect water leakage in conductive pipes such as metal pipes. That is, in order to detect leakage of water in a pipe or the like, the water-permeable insulating tape 1 must be opposed to the surface of the pipe, and the water leakage detection cable must be wound around the pipe. May be pressed to short-circuit between the conductors 3, and a water leakage signal may be generated regardless of the presence or absence of water leakage. Therefore, it cannot be used to detect water leakage in conductive pipes.
Further, even when laid on the floor surface, a conductive member may fall onto the water leak detection cable, causing a short circuit between the conductors 2 and generating an erroneous signal.

い。In the water leakage detection cable of the present invention having the above structure, the conductor bare wire is provided with a water permeable coating made of a braid of insulated wire material. Therefore, water that has entered the water leak detection cable is passed through the water permeable coating to the conductor bare wire. It is possible to make contact and short them to generate a water leak signal. Further, since the water-permeable coating is made of a braid of insulated wire, even when wound around a conductive pipe made of metal, for example,
Due to the action of the external force, the bare conductors are not short-circuited by the pipe, and an erroneous signal is not generated. Further, even when it is laid on the floor surface, there is no possibility that an erroneous signal is generated due to the conductive member dropping onto the water leak detection cable.
