<p>PROBLEM TO BE SOLVED: To provide a manufacturing method of a bus-bar wiring board by which the number of punching dies are reduced and the punching man-hours are reduced. SOLUTION: A plurality of bus bars with required patterns are arranged on a wiring board so as to have required positional relations and necessary tab-shaped terminals are formed on the respective bus bars. The bus bar wiring pattern 1 (or 2 or 3) of an arbitrary bus bar wiring layer is divided into a plurality of regions and the divided bus bar wiring patterns 1A and 1B are punched out of one conductive metal plate, together with the bus bar wiring patterns of other layers.</p> |
