    摘要： A production method of a wired circuit board that can prevent corrosion of a first thin metal film inwardly of a conductor layer, which is due to the forming of an undercut portion caused by a skirt portion of a plating resist, to prevent the peeling of a wiring circuit pattern. An insulating base layer 1 is prepared, first, and, then, a first thin metal film 2 is formed on the insulating base layer 1. Then, a plating resist 3 is formed in a reversal pattern to a wiring circuit pattern 4 on the first thin metal film 2, and a conductor layer 6 is formed in the wiring circuit pattern 4 on the first thin metal film 2 exposed form the plating resist 3. Thereafter, the plating resist 3 is removed and, then, a second thin metal film 8 is formed on the conductor layer 6 and first thin metal film 2. Thereafter, the second thin metal film 8 is removed. Then, all portions of the first thin metal layer 2, except portions thereof where the conductor layer 6 is formed, are removed. The flexible wired circuit board is produced by the processes described above.
