Abstract
A resin composition includes a resin A, a resin C, and a solvent. The resin A includes a sulfonic-acid-group-containing structural unit in an amount exceeding 5 mol % with respect to total structural units included in the resin A. The resin A has a content of a fluorine atom of 30 mass % or less with respect to a total mass of the resin A. The resin C includes a fluorine atom in a larger content per unit mass than the content of a fluorine atom per unit mass in the resin A. A content of the resin A in the resin composition is lower than a content of the resin C in the resin composition in terms of mass.
