The tape core wire 1 is separated into a single core wire 2 by cutting a tip of a tape-shaped coating. These single-core wires are housed in the reinforcing pipes one by one, and the heat-shrinkable tube 6 is put over the roots of these reinforcing pipes and the tip of the unseparated coating of the tape core wire 1. A reinforcing body 7 and a thermoplastic adhesive 8 are placed in the heat shrinkable tube 6. As a reinforcement,
A glass fiber or a metal fiber bundled and molded into a semi-cylindrical shape is used, but its length is set to be substantially equal to the length of the heat-shrinkable tube 6. As the thermoplastic adhesive 7, a tube-shaped product may be used in advance, but in that case as well, its length is made substantially equal to the length of the heat-shrinkable tube 6.

As described above, in the manufacturing method of the present invention, the reinforcing body 7 and the thermoplastic adhesive 8 are previously put between the tip of the coating of the tape core wire 1 which is not separated and the root of the reinforcing pipe 3. Since the heat-shrinkable tube 6 is covered to cause the heat-shrinkage, the thermoplastic adhesive 8 flows by the force at the time of the heat-shrink, and the tip of the coating in which the tape core wire 1 is not separated and the single core wire are separated. The exposed portion 2, the reinforcing body 7, and the base of the reinforcing pipe 3 are inserted into the exposed portion 2 to firmly bond them. The length of the reinforcing body 7 previously inserted into the heat-shrinkable tube 6 is substantially equal to that of the heat-shrinking tube 6, and both ends of the reinforcing body 7 have the ends of the coating of the tape core wire 1 not separated. Since it is adhered to the root of the reinforcing pipe 3 to reliably connect them, the mechanical strength is high. When the reinforcing body 7 is formed in a semi-cylindrical shape in advance, a plurality of single core wires 2 drawn out in parallel from the tape core wire 1 are arranged on the flat surface of the reinforcing body 7. Since the single-core wire 2 can be arranged, the reinforcing member 7 has an arcuate surface that fits well with the heat-shrinkable tube 6, and the heat-shrinkable tube 6 shrinks smoothly. It is rarely applied.
