摘要： To provide a copolymer capable of forming a coated electrical wire excellent in engine oil resistance, a composition, a molded product, and a coated electrical wire. The copolymer of the present invention is a copolymer comprising units based on ethylene, units based on tetrafluoroethylene, and units based on compound A represented by CH═CX(CF2)nY (wherein X and Y are each independently a hydrogen atom or a fluorine atom, and n is an integer of from 2 to 6) or compound B represented by CF2═CF—O—C3F7, wherein the crystal lamella thickness determined by the small angle X-ray scattering method is at most 4.0 nm and the melting point is at least 245° C.
