Claim:
A radiation-sensitive resin composition comprising: a compound represented by a following formula (1); a resin component comprising: a base resin having an acid-dissociable group, being insoluble or hardly soluble in an alkali, and being soluble in an alkali in a state where the acid-dissociable group is dissociated; and optionally, a radiation sensitive acid generator which is at least one selected from the group consisting of an onium salt, an organic halogen compound, and a sulfone compound, wherein, in the formula (1), R represents a hydrogen atom or a hydrocarbon group having 1 to 20 carbon atoms, R 1 represents a hydrocarbon group having 1 to 20 carbon atoms, and optionally an ester bond or an ether bond is included in a skeleton chain of the hydrocarbon group, R 2 to R 5 each independently represent an alkyl group having 1 to 4 carbon atoms or an alicyclic hydrocarbon group having 4 to 20 carbon atoms, R 6 represents a halogen atom or a hydrocarbon group having 1 to 6 carbon atoms, n is an integer of 0 to 4, and in a case where n is an integer of 2 to 4, R 6 present in a plurality of numbers are each a same or different.
