Abstract: A wired circuit board includes an insulating layer and a conductive layer. The insulating layer continuously has a first insulating portion, a second insulating portion having a thickness smaller than that of the first insulating portion, and a third insulating portion disposed between the first insulating portion and the second insulating portion and having a thickness that gradually becomes smaller from the first insulating portion toward the second insulating portion. The conductive layer continuously has a first conductive portion disposed at one-side surface of the first insulating portion and a second conductive portion disposed at one-side surface of the second insulating portion and having a thickness smaller than that of the first conductive portion. The first conductive portion is disposed at one-side surface of the second insulating portion and the third insulating portion or is disposed at one-side surface of the first insulating portion and the third insulating portion.

Abstract: A conductor trace is formed on a base insulating layer. The conductor trace includes two terminal portions and one wiring portion. The wiring portion is formed to connect the two terminal portions to each other and extend from each terminal portion. A metal cover layer is formed to cover the terminal portion and the wiring portion of the conductor trace and continuously extend from a surface of the terminal portion to a surface of the wiring portion. The metal cover layer is made of metal having magnetism lower than magnetism of nickel, and is made of gold, for example. A cover insulating layer is formed on the base insulating layer to cover a portion, of the metal cover layer formed on the conductor trace, covering the wiring portion and not to cover a portion of the metal cover layer covering the terminal portion.
