PROBLEM TO BE SOLVED: To easily separate a sheath and a water-barrier layer when a cable with the water-barrier layer adhering to the sheath is disassembled. SOLUTION: A conductor 1 is pulled out of the cable after the cable is dismounted, and the part except the conductor 1 is cut into a suitable size and shape. The portion of the sheath 7 (portion where the water-barrier layer 6 is adhered to the sheath with a polyolefin based adhesive or the like) of the thus broken-up cable is performed with wet and heat treatment. The wet and heat treatment is performed, for example, in a state that a specimen is exposed to a high_temperature (≥60°C) and a wet (10 to 100%) environment. Preferably, the portion of the sheath 7 of the broken-up cable is performed with wet and heat treatment by being immersed in hot water. COPYRIGHT: (C)2004,JPO
