ABSTRACT:
A double-sided flexible circuit board with enhanced rigidity of terminals by using copper foil on an opposite side of the circuit board is provided. The flexible circuit board having wiring patterns P for connecting terminals on each of a front surface A and a back surface B of its periphery, includes: terminal patterns with linear-planar-shaped traces, the traces of which are equally spaced and disposed on the peripheries of each of the front surface and the back surface of the board; and backing patterns with planar-shaped traces, the traces of which are combined with the terminal patterns and bent so that the central portion of the backing pattern is offset from that of the terminal pattern, wherein the traces of the backing patterns are disposed on the corresponding opposite side of the traces of the terminal patterns on the board so as to be positioned overlapping with the traces of the terminal patterns.
