Abstract: Soldering is performed with a high yield ratio even when extremely-thin wires are joined at an extremely-narrow pitch. Moreover, a bridge between conductive joint portions is reduced. A core wire 41 is placed on a preliminarily-soldered conductive joint portion 2. Then, the conductive joint portions 2 and the core wires 41 are covered with an optically-transparent sheet 30. Thus, the state in which the core wire 41 is placed on the conductive joint portion 2 is held. In this state, the optically-transparent sheet 30 is irradiated with light. A preliminary solder 3 is heated and melted to join the core wire 41 and the conductive joint portion 2 together.

Abstract: A shield wire is formed of eight twisted insulated core wires 1, an inclusion 2 between these respective insulated core wires 1, a tape 3 laterally wound around an outer periphery of a core formed of the insulated core wires and inclusion, a drain wire 4 disposed on an outer surface of the tape, a conductive fiber braided body 5 formed on an outer peripheral surface of the tape so as to interpose the drain wire, a sheath 6 that forms an outer peripheral surface of the braided body, and an adhesive layer 7 between the braided body and sheath. A braided body 5? is adhesively integrated to the sheath 6? by an adhesive layer; thus, the braided body 5? is stripped with the sheath. This eliminates a need for a removal work of the braided body after stripping the sheath, thus ensuring good workability of the terminal processing.
