Abstract
A thermoplastic liquid polymer film and a method of producing the same are provided. The method includes preparing a thermoplastic liquid crystal polymer film that has dielectric constants of not larger than 3.25 both in an MD direction and in a TD direction; and performing drawing of the film while heating the film at a temperature in a range from a temperature (Td-60° C.) that is 60° C. lower than a heat deformation temperature (Td) of the film to a temperature (Td-5° C.) that is 5° C. lower than Td. The temperature of the heating during the drawing of the film may be in a range from a temperature (Td-40° C.) that is 40° C. lower than a heat deformation temperature (Td) of the film subjected to the drawing to a temperature (Td-10° C.) that is 10° C. lower than Td.
