1. A metal-coated liquid-crystal polymer film comprising:
a polymer film main body comprising a polymer capable of forming an optically anisotropic melt phase, the polymer film main body having a first surface and a second surface opposite to the first surface;
a first metal layer layered on the first surface of the polymer film main body; and
a second metal layer layered on the first metal layer, wherein
the first metal layer has an average oxygen concentration of 2.5 atom % or less measured in a thickness direction over the entire thickness of the first metal layer using XPS.
