Abstract: A fluorine-containing copolymer including tetrafluoroethylene units (a), ethylene units (b), and hexafluoropropylene units (c), a content of the tetrafluoroethylene units (a) in the total monomer units being 36.0 to 45.0% by mole; a content of the hexafluoropropylene units (c) in the total monomer units being 6 to 21% by mole; a mole ratio of the tetrafluoroethylene units (a) to the sum of the tetrafluoroethylene units (a) and the ethylene units (b), (a)/((a)+(b)), being 0.40 to 0.54; and a melt flow rate measured under the conditions of 230° C. and a load of 5 kg being 12 to 100 g/10 minutes.
