PROBLEM TO BE SOLVED: To enhance the quality of the bending and working operation of a printed-circuit board. SOLUTION: In printed-circuit boards 50a, 50b which are connected by jumper wires and whose mounting operation is finished, a mark 55 is put in such a way that the edge-end-part side face 50a1 of the printed-circuit board 50a whose mounting operation is finished is situated on the edge-end-part end face 50b2 of the printed-circuit board 50b whose mounting operation is finished. A bending and working operation is performed in such a way that the edge-end-part side face 50a1 is situated on the mark 55. Thereby, without taking into consideration the positional relationship between the edge-end-part side faces 50a1 , 50b1 of the printed-circuit boards 50a, 50b whose mounting operation is finished, and the quality of the bending and working operation of a printed-circuit board 50 can be enhanced. |
