Claims

[Claims for Utility Model Registration] (1) At least a base film, a conductive electrical wiring pattern formed on both surfaces of the base film, and a base film for partially exposing the electrical wiring pattern. - In a double-sided flexible printed circuit board consisting of an insulating cover film that covers the electrical wiring pattern and the base film except for openings that face each other with the film interposed therebetween, of the openings that face each other, A flexible printed circuit board characterized in that the opening end of one opening and the opening end of the other opening are shifted by a predetermined amount. (2) At least a base film, a conductive electrical wiring pattern formed on one side of the base film, and an electrical wiring pattern excluding an opening for partially exposing the electrical wiring pattern. In a flexible printed circuit board consisting of an insulating cover film covering a base film, an opening end of the opening, which is a surface opposite to the surface on which the opening is formed through the base film; and a flexible printed circuit board, characterized in that a reinforcing layer is provided in a portion opposite to a region including a part of the exposed part of the electrical wiring pattern and a part of the cover film extending from the opening end.
