<P>PROBLEM TO BE SOLVED: To provide a water cut-off treatment method of electric wire and a water cut-off structure of electric wire, wherein a desired water cut-off effect can be obtained without spoiling at all flexibility required as the electric wire. <P>SOLUTION: An insulating coating of an electric wire consisting of a conductor and the insulating coating provided on the outer circumference of the conductor is partially peeled off to expose the conductor and polyurethane resin is dropped between the exposed conductor and the insulating coating to apply a water cut-off treatment. Since the polyurethane resin is used as a water cut-off material, flexibility as the electric wire is not spoiled even after curing. Furthermore, required water cut-off effect is certainly provided. <P>COPYRIGHT: (C)2010,JPO&INPIT |
