PROBLEM TO BE SOLVED: To effectively prevent crushing of conductive paste and to obtain a good wiring pattern without short circuitting, even in a case where printed wiring members are arranged and adhered at a specified wiring pitch and at a high density. SOLUTION: First printed wiring members 2a to be arranged in one direction and multiple second printed wiring members 2b to be arranged with a specified angle with respect to the first printed wiring members 2a are adhered to the top of an insulating board. Edges of the second printed wiring members 2b are overlaid on the edges of the first printed wiring members 2a to electrically connect them and to form a wiring board. Each of the first printed wiring members 2a is provided with two bifurcations or more at its edge and the width of the edge of the second printed wiring members is to be narrower than the bifurcation of the first printed wiring members 2a. |
