Abstract: Provided are a fluorine-containing compound suitable to produce rubber having both excellent short-term and long-term heat resistance, a fluorine-containing copolymer using such a compound, and a fluorine-containing copolymer composition. A fluorine-containing compound represented by formula (1) below, a fluorine-containing copolymer using such a compound, and a fluorine-containing copolymer composition. In formula (1), R1 to R3 are each independently a hydrogen atom or a fluorine atom; R4 is a hydrogen atom, a fluorine atom, or a C1-8 monovalent organic group free from a carbonyl group; Z is an oxygen atom, a sulfur atom, or —N(R5)— where R5 is a hydrogen atom or a C1-4 monovalent organic group; X is a single bond or a difluoromethylene group; Y1 to Y4 are each independently a fluorine atom or a trifluoromethyl group; and Q is a C1-8 perfluoroalkylene group optionally containing an etheric oxygen atom.
