Zusammenfassung:	PROBLEM TO BE SOLVED: To timely catch a microcrack of an electroconductive wire which is generated due to repeated bending of a flexible printed circuit board accompanied by high-speed motion of a robot.SOLUTION: Both a board body 30-2 and an electroconductive wire 27-2 for inspection of an FPC board 14-2 have materials and shapes the same as those of a board body 30-1 and a main electroconductive wire 27-1 of a main FPC board 14-1. The FPC board 14-2 for inspection is provided alongside in the thickness direction of the main FPC board 14-1, and also the operating conditions are the same. The position of a reversing portion T of the FPC board 14-2 for inspection is inside the main FPC board 14-1. This results in a fatigue deterioration speed of the FPC board 14-2 for inspection slightly faster than that of the main FPC board 14-1.
