FLEXIBLE PRINTED WIRING BOARD, ELECTRONIC DEVICE HAVING FLEXIBLE PRINTED WIRING BOARD, METHOD FOR MANUFACTURING ELECTRONIC DEVICE HAVING FLEXIBLE PRINTED WIRING BOARD

摘要

To provide a flexible printed wiring board which can satisfactorily increase the connection strength of a welded portion with an electrode of a battery.SOLUTION: A flexible printed wiring board comprises a flexible insulative layer and a conductor layer formed on at least one face of the flexible insulative layer, and it has a first principal face and a second principal face on a side opposite to the first principal face. In the flexible printed wiring board, a hole extending therethrough from the first principal face to the second principal face is formed; a columnar metal body having two bottom faces is fit in the hole. One of the bottom faces of the metal body is to be connected to a battery electrode by welding. During the welding, the metal body makes a welding base material. The metal body is formed from the same material as that of the battery electrode.SELECTED DRAWING: Figure 1
