PROBLEM TO BE SOLVED: To provide a flat cable in which generation of a whisker is sufficiently suppressed and also increase of contact resistance is suppressed, and a manufacturing method to manufacture the flat cable. SOLUTION: This is a flat cable 1 in which a plurality of rectangular conductors 2 arranged in parallel are covered by an insulating film 3. The rectangular conductors 2 have an alloy layer 12 made of an alloy in which bismuth and zinc are contained in tin formed on the surface of a base material 11 made of copper or copper alloy, and the alloy layer 12 contains bismuth of 1.0 wt.% or more and 4.0 wt.% or less and zinc of 0.2 wt.% or more and 2.0 wt.% or less against tin, and the thickness is 0.3μm or more and 0.9μm or less.
