Patent ID: 7525764

Claim:
A suspension board with a circuit, which comprises a metal board comprising an area for mounting a magnetic head, and other area comprising a conductive layer provided on the metal board as a circuit pattern via an insulation layer, the aforementioned circuit pattern having a pattern end to be a terminal to be connected with a terminal of a magnetic head, and the end face of the pattern end is aligned with the end face of the insulation layer directly beneath, or protruding from the end face of the insulation layer in the terminating direction, wherein the metal board has an opening penetrating the board on the terminating side of the pattern end and an inner wall surface of the opening is retracted to a position beneath the insulation layer, and wherein the pattern end protrudes in the terminating direction from the end face of an insulation layer directly beneath it, then bends toward the lower layer side, covering the end face of the insulation layer, and further bends in the terminating direction, whereby a stepped-part is made on the upper surface of the pattern end, with a lower level on the tip side.
