  • Patent number: 9972417
    Abstract: An electrically conducting path including: an electrical wire; an exterior member made of rubber and enclosing a portion of the electrical wire; a waterproof member filling a gap between an opening part of an end portion of the exterior member and the electrical wire; and a molded resin member that is in intimate contact with and covers, in a liquid-tight state, an outer circumferential surface of the end portion of the exterior member, the waterproof member, and a section of the electrical wire that is exposed to an outside of the exterior member. Since the gap between the opening part of the end portion of the exterior member and the electrical wire is sealed in a liquid-tight state by the waterproof member and the molded resin member, it is possible to prevent water from entering the inside of the exterior member.
