Abstract

Provide is a metal-coated liquid-crystal polymer film that is suitable for microcircuit processing and capable of reducing the transmission loss of circuits. The metal-coated liquid-crystal polymer film comprising: a polymer film comprising a polymer film main body capable of forming an optically anisotropic melt phase; a first metal layer layered on at least one side of the polymer film main body; and a second metal layer layered on the first metal layer, wherein in an analysis of oxygen concentration in a thickness direction using XPS, the average oxygen concentration of the first metal layer is 2.5 atom % or less.
