ABSTRACT:
A liquid-crystal polymer film with a melting point of 335° C. or greater and high surface accuracy, and specifically with a surface roughness Ra of 0.1 μm or less both in the machine direction and in the transverse direction, and a manufacturing method thereof.A method for manufacturing a liquid-crystal polymer film with a melting point of 335° C. or greater and a surface roughness Ra of 0.1 μm or less both in the machine direction and in the transverse direction, characterized in that a laminate of a fluororesin porous film and a resin film made from a liquid-crystal polymer or a polymer alloy containing a liquid-crystal polymer is drawn, and the fluororesin porous film is peeled off.
