A radiation-sensitive resin composition includes: a base resin comprising a structure unit having an acid-dissociable group; and a radiation-sensitive acid generator which comprises compounds represented by formula (2) and formula (3), and optionally a compound represented by formula (1). R1-R3 are each independently a group having a cyclic structure. X11-X32 are each independently a hydrogen atom, a fluorine atom, or a fluorinated hydrocarbon group. At least one of X11 or X12, at least one of X21 or X22, and at least one of X31 or X32 are not a hydrogen atom, respectively. A11-A32 are each independently a hydrogen atom, or a hydrocarbon group having a carbon number of 1 to 20. The radiation-sensitive resin composition does not comprise a ketone-based solvent. The the radiation-sensitive resin composition does not comprise a monovalent onium cation other than an onium cation represented by formulas (X-1), (X-3), (X-4), or (X-5).
