A tetrafluoroethylene copolymer comprising 30 to 81 mole % of tetrafluoroethylene and a 70 to 19 mole % of at least one other monomer, and having terminal carbonate groups at polymer chain ends, which has a melt flow rate of 0.1 to 100 g/10 min. at 200° C. under a load of 5 kg, and a melting point of 90 to 200° C. This copolymer can be firmly adhered directly to other materials such as general-purpose resins while maintaining the good properties of fluororesins such as chemical resistance, weather resistance, solvent resistance, non-tackiness, electrical insulation, stain-proofing properties, and flame retardance, molded at a lower temperature than conventional fluororesins, and heat bonded or co-extruded with general-purpose resins having low heat resistance.
