Abstract
A fluorine-containing resin composition of the present invention includes: a fluorine-containing resin; and a solvent in which the fluorine-containing resin is dissolved. The solvent is a perfluoroalkene. The fluorine-containing resin includes a fluorine-containing polymer including a structural unit (A) represented by the following formula (1). (In the formula (1), Rff1 to Rff4 each independently represent a fluorine atom, a perfluoroalkyl group having 1 to 7 carbon atoms, or a perfluoroalkyl ether group having 1 to 7 carbon atoms. Rff1 and Rff2 are optionally linked to form a ring.)
