A resin composition for forming a phase-separated structure containing a block copolymer having a first block and a second block, in which the first block is formed of a constituent unit represented by Formula (b1), the second block is formed of a constituent unit represented by Formula (b2m) and a random copolymer having a constituent unit represented by Formula (b2g), and a ratio of a volume of the first block is 20% to 80% by volume. In the formulas, R 1 is a hydrogen atom or an alkyl group, R b1 is a hydrogen atom or a methyl group, R 2 is an alkyl group which may have a silicon atom, a fluorine atom, a carboxy group, an amino group, a hydroxy group, or a phosphoric acid group, R 3 is a linear or branched alkylene group having 1 to 10 carbon atoms, which may have a hydroxy group, and R b2 is a hydrogen atom, an alkyl group having 1 to 5 carbon atoms, or a halogenated alkyl group having 1 to 5 carbon atoms |
