Patent ID: 7407386

Claim:
A wired circuit board comprising: an insulating base layer; a conductive pattern formed on the insulating base layer; and an insulating cover layer formed on the insulating base layer for covering the conductive pattern, wherein the conductive pattern includes terminal portions for connecting with external terminals; the insulating cover layer has an opening formed correspondingly for the respective terminal portions; and a position determining zone, for determining whether or not a margin of the insulating cover layer facing the opening is located in a proper position, is provided in the proximity of the terminal portions, wherein the position determining zone is formed to extend along a direction of the margin of the insulating cover layer, and wherein the position determining zone is defined by a pair of determining marks which are disposed opposite to each other in a direction intersecting with the direction along the margin of the insulating cover layer and are spaced apart by an amount to allow tolerance to an area where the margin of the insulating cover layer is formed.
