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.

Metal-coated liquid-crystal polymer film

A resin composition includes a polymer (A) mainly containing a structural unit represented by following Formula (1): 

Gas-barrier resin composition

A polymer consisting mainly of structural units represented by the general formula (1), wherein the total molar amount of terminal aldehyde groups and acetal groups is 0.6 mol % or smaller based on the total molar amount of the structural units represented by the general formula (1). &#x2014;[&#x2014;(&#x2014;CHR&#x2014;)&#x2014;CXR&#x2014;CXR-]&#x2014; (1) (In the formula, n is an integer of 2 to 10; Xand Xeach represents &#x2014;H, &#x2014;OH, or a functional group capable of being converted into &#x2014;OH, provided that at least one of Xand Xis hydroxy or a functional group capable of being converted into hydroxy; and R, R, and Reach represents &#x2014;H or Calkyl, aryl, aralkyl, or heteroaryl and the two or more R's may be different).
