PROBLEM TO BE SOLVED: To provide an aqueous dispersion containing a high concentration of fluoropolymer particles, wherein the pH is less prone to fluctuate and an aggregate is less prone to be produced even in long-term storage.SOLUTION: An aqueous dispersion is characterized by containing 50-70 mass% of fluoropolymer particles having a mean primary grain size of 0.1-0.5 μm, 2-10 mass% of a non-ionic surfactant in relation to the fluoropolymer, and 0.0001-1 mass% of ammonium lauryl sulfate in relation to the fluoropolymer, the amount of fluorine-containing anionic surfactant contained being less than 10 ppm. |
