Problems to be Solved There is provided a dispersion composition of fluorine-containing ion exchange resin, which has an extremely low solution viscosity even in a case in which the concentration of a fluorine-containing ion exchange resin is increased by a concentration operation in a liquid composition in which the fluorine-containing ion exchange resin is dispersed. Solution A dispersion composition of fluorine-containing ion exchange resin, which comprises a fluorine-containing ion exchange resin having a repeating unit represented by the following formulae (1) and (2) and having an equivalent weight of 400 to 1000 g/eq, and a solvent containing water, wherein Z represents H, Cl, F, or a perfluoroalkyl group containing 1 to 3 carbon atoms; m represents an integer of 0 to 12; and n represents an integer of 0 to 2, and wherein an abundance ratio of a resin having a particle size of 10μm or more in the fluorine-containing ion exchange resin is 0.1% to 80% by volume.
