Abstract
A wired circuit board for electrically connecting a suspension board with circuit comprising a metal supporting layer, an insulating base layer, a conductive layer, and an insulating cover layer, and an external circuit, includes a first wired circuit board electrically connected with the suspension board with circuit; and a second wired circuit board for electrically connecting with the external circuit. The first wired circuit board and the second wired circuit board are electrically connected through a preamplifier. The first wired circuit board includes a first metal supporting layer; a first insulating base layer; a first conductive layer and a first insulating cover layer.
