ABSTRACT:
A wired circuit board includes 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. The insulating layer is formed with a groove exposing the metal supporting board between at least two adjacent wires, and the semiconductive layer is in contact with the metal supporting board in the groove.
