PROBLEM TO BE SOLVED: To provide a wiring material which constitutes a branch connection capable of carrying a large current, which are suitable for a wire harness on board or the like with flexibility and high adaptability of wiring and which is inexpensive and easy to form. SOLUTION: This consists of a circuit conductor 2 and an insulator 5 coating this circuit conductor 2, and the circuit conductor 2 consists of plural laminated sheets of copper foil pattern materials 3. The copper foil pattern materials 3 are formed of copper foils punched out in a shape of a circuit having branches. Plural sheets of the copper foil pattern materials 3 are formed in the same shape and these are laminated without being adhered to each other, thus the circuit conductor 2 is formed.
