Abstract:
1. A method of manufacturing a wiring material having a connecting terminal electrically connected to two single line conductors provided in parallel, comprising the steps of: forming a tube-shaped section for accommodating the two single line conductors at the connecting terminal; inserting the two single line conductors into the tube-shaped section having a circular cross section; and conducting a resistance welding by energizing a pair of welding electrodes, at least one of the welding electrodes having a round-shaped tip portion, from an outer periphery of the tube-shaped section having the circular cross section to electrically connect the connecting terminal with the two single line conductors, in a state where a part of the tube-shaped section located between the two single line conductors is pushed by the welding electrode having the round-shaped tip portion into a space formed between the two single line conductors such that an inner periphery portion of the tube-shaped section and the single line conductors are in contact with each other.
