PURPOSE:To run a large electric current by making the other printed wiring board connector conduction portion shorter than a flexible printed wiring board connector conduction portion in a connector conduction portion extension direction. CONSTITUTION:The lower side printed wiring board 2 connector conduction portion 2a is made shorter than a flexible printed wiring board 1 connector conduction portion 1a in a conduction portion extension direction, and these portions are pressed with an elastic body 8 by means of a connector metal tool 7. As a result, the portions 1a and 2a are to be welded under pressure most strongly at a portion 2a end surface 2c. Accordingly, the end surface 2c obtains the maximum load at the minimum area, and push-pressing load per unit area also rises, so the reduction of contact resistance, the improvement of reliability and the reduction of defective contact can be realized. |
