Abstract
A metal-clad laminate excellent in isotropy, appearance, bondability between a TLC polymer film and a metallic sheet, and dimensional stability is provided less costly with a first step of thermally compressing the film with the metallic sheet by passing them through a nipping region between heating rolls, and a second step of heat-treating the resultant metal-clad laminate at a temperature not higher than the melting point of the film, wherein the film has thermal expansion coefficient αsatisfying α=βT+γ with thickness T, thickness coefficient β and anisotropy coefficient γ of the film; wherein the coefficient β is within the range of −0.08 to −0.01; the coefficient γ is within the range of α+6≦γ≦α+10 with thermal expansion coefficient αof the metallic sheet; and thermal expansion coefficient αof the film is within α−2≦α≦α+3 with the coefficient α.
