A laminated film is obtained by laminating, through a liquid crystal polymer layer, a thermoplastic polymer layer which is adhesive to the liquid crystal polymer layer, on a thermoplastic polymer layer which is not adhesive to the liquid crystal polymer layer, such lamination being made in a co-extrusion molding machine, by extruding the laminated layers from a die and by separating the non-adhesive thermoplastic polymer layer from the liquid crystal polymer layer. The adhesive thermoplastic polymer layer is preferably formed by a modified polyolefin into which a functional group is being introduced. The non-adhesive thermoplastic polymer layer is preferably formed by an olefin polymer or a polyalkylene terephthalate.
