Abstract
The present invention aims to provide an aqueous dispersion that contains particles of a fluoropolymer at high concentrations and has a less variable pH, and in which aggregates are less likely to be generated even after the aqueous dispersion has been stored for a long time. The present invention relates to an aqueous dispersion, including: particles of a fluoropolymer having an average primary particle size of 0.1 to 0.5 μm in an amount of 50 to 70% by mass; a nonionic surfactant in an amount of 2 to 10% by mass based on the amount of the fluoropolymer; and ammonium lauryl sulfate in an amount of 0.0001 to 1% by mass based on the amount of the fluoropolymer, wherein an amount of a fluorine-containing anionic surfactant is less than 10 ppm.
