PROBLEM TO BE SOLVED: To provide a water infiltration detection structure capable of preventing an inter-wire short circuit by detecting water infiltration into a cylindrical member housing wires and cables. SOLUTION: The water infiltration detection structure 31 is composed of a metal protecting tube 32, a plurality of cables with water infiltration detection function 33 housed inside the metal protecting tube 32, an insulator 34 covering an outside of the metal protecting tube 32, a grounding wire 35 connected to the metal protecting tube 32, and a current detecting means 36 connected to the grounding wire 35. The cable with water infiltration detection function 33 is structured of a wire 37, a conductive layer 38 with conductivity provided outside the wire 37, and a water-absorbing insulation layer 39 with a water-absorbing property and insulation property provided outside the conductive layer 38. The wire 37 is structured of a conductor 40 and an insulator 41 provided on the conductor 40. COPYRIGHT: (C)2009,JPO&INPIT |
