Abstract
A wired circuit board that can provide an enhanced adhesion of a metal supporting board at a marginal portion of an opening formed in the metal supporting board with a simple structure to prevent stripping of the metal supporting board. In a suspension board with circuit, in order to reduce a transmission loss of a conductive pattern, a metal foil embedded in an insulating base layer is formed in a pattern comprising a first metal foil portion and a second metal foil portion surrounding the first metal foil portion spaced apart therefrom, and an opening is formed in the metal supporting board so that a marginal portion of the opening is located in a space between the first metal foil portion and the second metal foil portion.
