The present invention relates to a radiation-sensitive resin composition that contains: a compound that has a structure represented by the following formula (1); a first polymer that includes a fluorine atom; and a solvent. In the following formula (1), X represents a carbonyl group, a sulfonyl group or a single bond. Y+ represents a monovalent radiation-degradable onium cation. The first polymer preferably has at least one selected from the group consisting of a structural unit represented by the following formula (2a) and a structural unit represented by the following formula (2b). The first polymer preferably includes an alkali-labile group. The first polymer preferably includes an acid-labile group. It is preferred that a radiation-sensitive acid generator is further contained.
