Abstract: An object of the present invention is to provide an aqueous dispersion capable of forming a coating film excellent in coloring stability, a method for producing the aqueous dispersion, an aqueous coating material and a coated article. This aqueous dispersion comprises water, a surfactant and a fluorinated polymer, wherein the fluorinated polymer is dispersed in the water, wherein the fluorinated polymer comprises units based a fluoroolefin and units based on a monomer having a hydrophilic group, and the surfactant is a compound of such a structure that to a benzene ring, 1 group represented by the formula —(OQ)nOSO3−X+ and 2 to 4 phenyl alkyl groups are bonded (where Q represents a C2-4 alkylene group, n represents an integer of from 2 to 48, and X+ represents Na+ or NH4+).
