PROBLEM TO BE SOLVED: To protect the connector of a printed circuit board against damages, when a flexible wiring material is obliquely inserted into the connector of the printed circuit board. SOLUTION: The power supply line 21 and interconnection 22 of the flexible wiring material 2 are electrically connected to the power supply line 11, signal lines 12, ground interconnection 13, etc. of the printed circuit board 1, respectively, by inserting the flexible wiring material 2 into the connector 3 located on the printed circuit board 1. Capacitor-connected interconnections 14, equipped with capacitive circuit elements 14a, are provided adjacent to the power supply line 11 of the printed circuit board 1, and connected to the ground of the printed circuit board 1 so as to prevent damages to equipment due to the oblique insertion of the flexible wiring material 2. When the flexible wiring material 2 is inserted obliquely, the capacitor-connected interconnections 14 coming into incorrect contact with the power supply line 21 serve as high impedance in DC, and current will not flow through the capacitor-connected interconnections 14.
