Abstract

Provided is a fluoropolymer aqueous dispersion comprising: a polymer (I) having a hydrophilic group; a fluoropolymer; a nonionic surfactant (a) having an HLB of more than 8; and an aqueous medium, wherein the dispersion is substantially free from a fluorine-containing surfactant, a content of the fluoropolymer is 40% by mass or more and 70% by mass or less based on the fluoropolymer aqueous dispersion, a content of the nonionic surfactant (a) is 4.0% by mass or more and 12% by mass or less based on the fluoropolymer, and a height of foam of the fluoropolymer aqueous dispersion generated by a foamability test is 140 mm or less.
