PROBLEM TO BE SOLVED: To provide an isometric wiring substrate to which a large current is applied. SOLUTION: The wiring of composite structure configured of a metal plate made from such metal as copper and includes an isometric branch wiring member which branches in isometric manner once or more times, is provided on an insulator substrate. The isometric branch wiring member branches in tournament manner. A plurality of tournaments can be combined together. The number of branching times can be set at one's discretion. The wiring containing a large current wiring member which is formed from a copper plate made from such metal as copper and to which a plurality of isometric printed wirings are connected, is provided on the insulator substrate.
