Abstract:
1. A wired circuit board comprising: a metal supporting board; an insulating layer formed on the metal supporting board; a conductive pattern formed on the insulating layer and having a plurality of wires; and a semiconductive layer formed on a surface of the insulating layer exposed from the conductive pattern so as to be in contact with the conductive pattern, wherein the insulating layer is formed with a groove exposing the metal supporting board between at least two adjacent wires among the wires, such that a first insulating layer portion of the insulating layer is formed on one side of the groove and a second insulating layer portion of the insulating layer is formed on an opposite side of the groove, wherein the semiconductive layer comprises a first semiconductive layer portion formed on the first insulating layer portion and in contact with one of the two adjacent wires, and a second semiconductive layer portion formed on the second insulating layer portion and in contact with another of the two adjacent wires, and wherein the first semiconductive layer portion and the second semiconductive layer portion are each in contact with the metal supporting board in the groove.
