An object of the present invention is to provide a powder coating material and a fluoropolymer capable of forming a coating film which is excellent in impact resistance, flexibility, and adhesion to a substrate, and which has excellent surface smoothness even under low-temperature film formation conditions. The powder coating of the present invention includes a fluoropolymer including a fluoroolefin-based unit, a unit based on a monomer represented by the formula XZ, and a formula based on the formula CHR 21 = CR 22 (CH 2 ) n The unit of the monomer represented by COOH, and the content of the unit based on the monomer represented by the formula XZ with respect to all units contained in the fluoropolymer is 5 to 20 mol%. Melt viscosity is 20 to 100 Pa ยท s (where X is a specific monovalent polymerizable group, Z is a specific alkyl group, a specific cycloalkyl group, or a specific aryl group, and R 21 and R 22 are each independently a hydrogen atom or a specific alkane Base, n is an integer from 0 to 12). |
