PURPOSE:To prevent disconnection and to improve reliability by providing a part wherein external force is applied to a specified position and by forming a pattern wiring in an area near the part of an electric wire. CONSTITUTION:A printed circuit board 5 is provided with a part 1 wherein external force is applied to a specified position and a pattern wiring in an area near the part 1 is formed of an electric wire 2. That is, the part 1 wherein external force is applied is made a division line which divides the printed circuit board 5 after mounting of the part and the division line is formed to divide a corner edge part 3 which is a dummy part of the square printed substrate 5. Therefore, when external force is actually applied to the part 1 whereto external force is applied, the printed circuit board 5 is elastically deformed due to the external force; however, since a pattern wiring in an area near the part 1 whereto external force is applied is formed of the electric wire 2, disconnection of a copper foil, etc., can be prevented. Furthermore, since the electric wire 2 is not disconnected due to external force such as impact applied during division of the printed circuit board 5, product defective can be reduced. |
