ABSTRACT:
In a pattern structure of a flexible print circuit board, a plurality of electric signal transmitting patterns are formed as thin as possible as well as one of at least two void patterns is formed between the electric signal transmitting patterns and cut portions are formed to the respective void patterns so that they are directed in the bending direction of the flexible print circuit board. With this arrangement, the flexible print circuit board can be accurately and easily bent at a bending position without the need of a metal mold and special index patterns.
