Abstract:
A flexible printed circuit having wiring patterns printed on a flexible resin film, comprising:a narrow flexible area having first wiring patterns and constituting a flexible wiring part;a broad connection area adapted to be adhered to a main board and having second wiring patterns connected to the first wiring patterns and adapted to be electrically connected to wiring patterns on the main board, said second wiring patterns serving to electrically connect the first wiring patterns of the flexible wiring part to the wiring patterns on the main board; anda conductive adhesion surface formed on said broad connection area along a side of the main board, having a width larger than a width of the first wiring patterns, and extending from an inside of a region to an outside thereof, the region being defined in said broad connection area by extending a boundary of said flexible area into said broad connection area,wherein said conductive adhesion surface is an anchor pattern and is not required to establish electric connection between said first wiring patterns to the wiring patterns on the main board.
