Abstract
A method of producing a metal laminate for a circuit board includes a first step of press-bonding a thermotropic liquid crystal polymer film having a segment orientation ratio SOR within a range not smaller than 0.90 and smaller than 1.15 along the longitudinal direction of the film, to a metal sheet between hot rolls while the thermotropic liquid crystal polymer film is in a tense or non-tense state; and a second step of heating the laminate obtained in the first step to a temperature not lower than the melting point of the thermotropic liquid crystal polymer film.
