Before dispersing the catalyst particles (P3), which are carbon particles (P1) supporting a catalyst material (P2), and a polymer electrolyte (PE) in a solvent (S) for a catalyst ink, the carbon particles (P1) are exposed to a humidified atmosphere (M). The moisture content of the catalyst particles (P3) is from 4.8 mass% to 20 mas%, inclusive.",
