Abstract
To stably produce a laminate wherein heat resistant resin layers are laminated on both surfaces of a fluorinated resin layer, by thermal lamination. A process for producing a laminate, which comprises a preliminary heating step of heating, while conveying by a metal rollfor heating and a metal rollfor thermal lamination without pressing in the thickness direction, a temporary laminate wherein heat resistant resin filmsandare laminated on both surfaces of a fluorinated resin filmcontaining a melt-moldable fluorinated resin (A) having at least one type of functional groups selected from the group consisting of a carbonyl group-containing group, a hydroxyl group, an epoxy group and an isocyanate group and after the preliminary heating step, a thermal lamination step of pressing the temporary laminate in the thickness direction, while heating it by metal rollsandfor thermal lamination at a thermal lamination temperature of at least the melting point of the fluorinated resin (A) ant at most 420° C., for bonding.
