Abstract: PURPOSE:To improve a flexible printed wiring board in high temperature resistance, continual heat resistance, an electrical property and workability by a method wherein a conductor circuit is formed directly on a polyimide film to form a wiring board, and a cover coat containing polyparabanic acid and epoxy resin is formed on the side of the conductor circuit of the board. CONSTITUTION:A conductor circuit 13 is formed directly on a polyimide film 11, and then a cover coat 15 is printed on the conductor circuit formed surface with material which contains polyparabanic acid through a printing method, which is set at a low temperature. The conductor circuit is formed directly on the polyimide film through the following methods: a method where polyimide resin is applied directly on the surface of a thin conductive material such as a copper foil, which is set through heating, and a formed copper plated board is formed into a conductor circuit through a subtractive method; a method where a circuit is formed directly on a polyimide film through an additive method. By these processes, an FPC, excellent in a high temperature resistance and continual heat resistance, can be obtained. As a pasting operation of a film can be dispensed with and a cover coat is formed through a printing, so that a printed wiring board of this design is excellent in workability and productivity and consequently a FPC of high reliability can be realized.
