PURPOSE:To detect automatically the occurrence position of water leaking in a room where a computer, etc., is installed by one sensor cable by leading a voltage corresponding to the position where the water leak occurs out of one end of the sensor cable. CONSTITUTION:When there is no water leaking, an insulator 2 is in a high insulation state between conductor cables 2a and 2b and no voltage is developed between terminals (a) and (b). In this state, if water leaks and covers the coating part of the sensor cable 2, the surface of the insulator at the part and the coating part of the cable are dipped in the water and the insulation at the intermediate point between the conductor cables 2a and 2b is broken to cause a short circuit by low resistance. Consequently, a voltage indicating the intermediate position of the conductor cable 2a is developed between the terminals (b) and (a) and applied to a rectifying circuit 3. For the purpose, the voltage value is read on a meter 4 to know the water leak position.
