PURPOSE:To make strength and adhesiveness in a direction TD of the title film excellent, by a method wherein extrusion is performed in a multi-layer under a state where at least a thermoplastic polymer layer having adhesiveness to a liquid crystal polymer layer is formed by making use of a molding machine. CONSTITUTION:A liquid crystal polymer comprised of polyester A constituted of repeating units I, II is fed to a flow path 1 out of a coextrusion molding machine by making use of an extrusion machine. Glycidyl modified polyethylene is fed respectively to flow paths 2a, 2b by making use of the extrusion machine. With this construction, a multi-layer film where adhesive thermoplastic polymer layers 12a, 12b are laminated respectively to both the surfaces of a liquid crystal polymer layer 11 is manufactured. |
