Abstract

Provided is a method for producing a metal-clad laminate of a thermoplastic liquid crystal polymer film (TLCP film) and a metal sheet(s) bonded to at least one surface of the film using roll-to-roll processing. The metal sheet has a surface with a ten-point average roughness (Rz) of 5.0 μm or less to be bonded to the TLCP film. The method includes preparing the laminate, dry-treating the laminate by subjecting the laminate passed through a dry zone satisfying the following conditions (1) and (2): heat-treating the dried laminate by subjecting the laminate passed through a heating zone on a temperature condition of not lower than the melting point of the TLCP film successively after the dry treatment.
