Abstract: The disclosure provides an aqueous dispersion that can provide a film having excellent weather resistance and excellent hardness and that has excellent dispersion stability. The aqueous dispersion contains a fluorine-containing polymer that contains: a polymerized unit (a) based on a fluorine-containing monomer; a polymerized unit (b) based on a carboxy group-containing monomer; and a polymerized unit (c) based on a hydroxy group-containing monomer. The polymerized unit (b) is contained in an amount of 4.0 to 14.0 mol % of all polymerized units and the polymerized unit (c) is contained in an amount of 14.0 to 35.0 mol % of all polymerized units.
