ABSTRACT:
A method of making a thermotropic liquid crystal polymer film includes continuously heat treating of the thermotropic liquid crystal polymer film2while the latter is jointed to a sheet-like support member4, and subsequently separating the heat-treated thermotropic liquid crystal polymer film2from the support member4. The continuous heat treatment of the thermotropic liquid crystal polymer film2then jointed to the support member4is carried out for a predetermined heating time within the range of 5 to 60 seconds at a predetermined heating temperature T° C. equal to or higher than the melting point Tm° C. of the thermotropic liquid crystal polymer film less 15° C. (i.e., Tm−15° C.), but lower than the melting point Tm° C. (thus, Tm−15° C.≦T° C.<Tm° C.), to thereby increase the thermal expansion coefficient of the thermotropic liquid crystal polymer film.
