Claim Text:
1. A flexible flat circuit, comprising: a pair of insulation sheets; and a plurality of conductors comprising a first conductor and a second conductor disposed between and covered with the pair of insulation sheets such that the plurality of conductors do not contact each other, the first conductor has a greater width and thickness and current carrying capacity that the second conductor, and the top faces of the first and second conductors are flush with each other, wherein the entirety of the first and second conductors are disposed between and covered with the pair of insulation sheets, wherein the first conductor is embedded in one of the pair of insulation sheets and the second conductor is provided on a surface of the one of the pair of insulation sheets, and wherein a fuse circuit is formed on the second conductor by stacking a metallic layer on an S-shaped section of the second conductor, the metallic layer having a melting point lower than a melting point of a material of the second conductor.
