A liquid crystal polymer film that includes: a benzene ring; a naphthalene ring; and a carboxymethyl group, wherein, in aC-NMR spectrum of a liquid crystal polymer film decomposed with supercritical methanol, an integral value CA of a peak derived from the benzene ring, an integral value CB of a peak derived from the naphthalene ring, and an integral value CC of a peak derived from the carboxymethyl group satisfy (CA+CB)/CC of 1.35 to 1.65.

Liquid crystal polymer film, liquid crystal polymer film with conductor layer, and multilayer substrate

A metal-clad laminate that includes a metal foil with low surface roughness and in which the adhesion strength between a liquid crystal polymer film and the metal foil is high, the low transmission loss in a high frequency region is low, and the problems associated with warpage and adhesive leakage are alleviated. The metal-clad laminate includes the liquid crystal polymer film, an adhesive layer, and the metal foil, with the adhesive layer and the metal foil stacked on one surface of the liquid crystal polymer film.
