Abstract
A flat cable includes a plurality of flat conductors each including a copper substrate, the flat conductors being aligned in a plane, and an insulating resin that covers the flat conductors. At least a terminal part of each of the flat conductors has a tin-copper alloy layer on the copper substrate, and a zinc-containing tin plating layer on the tin-copper alloy layers. The thickness of the tin-copper alloy layer is at least 0.2 μm and not greater than 1.0 μm. The thickness of the zinc-containing tin plating layer is at least 0.2 μm and not greater than 1.5 μm. The total thickness of the tin-copper alloy layer and the zinc-containing tin plating layers is at least 0.4 μm and not greater than 1.7 μm.
