ABSTRACT:
A fluorocopolymer film formed by molding at a molding temperature of at most 320° C. a fluorocopolymer comprising repeating units based on ethylene, repeating units based on tetrafluoroethylene, repeating units based on hexafluoropropylene and repeating units based on a fluoroalkyl vinyl ether represented by CF2═CFORf(wherein Rfrepresents a C1-10fluoroalkyl group), having a molar ratio of the repeating units based on ethylene/the repeating units based on tetrafluoroethylene of from 10/90 to 60/40, a content of the repeating units based on hexafluoropropylene to the total repeating units of from 0.1 to 20 mol % and a content of the fluoroalkyl vinyl ether to the total repeating units of from 0.1 to 10 mol %, and having a volumetric flow rate of from 0.1 to 30 mm3/sec at 297° C.
