<P>PROBLEM TO BE SOLVED: To provide a flexible printed circuit board that is bent without any contamination, and facilitates keeping a bent state. <P>SOLUTION: The flexible printed circuit board 30 includes copper wirings 2 and insulating layers 1, 3 positioned in the upper and lower parts of each copper wiring. A dissimilar material 5 different from the copper wiring 2 is positioned between the upper and lower insulating layers. Thus, when the flexible printed circuit board is bent, the bent parts K<SB>1</SB>, K<SB>2</SB>keep the bent shapes. <P>COPYRIGHT: (C)2011,JPO&INPIT |
