A radiation-sensitive resin composition includes an acid-labile group-containing resin, a radiation-sensitive acid generating agent, and an acid diffusion controller including a first compound shown by a following general formula (1-1) and a second compound shown by a following general formula (1-2) or (1-3). In the formula (1-1), each of R1 and R2 individually represents a hydrogen atom or the like, and Rp represents an acid-labile group. In the formula (1-2), R3 represents a hydrogen atom or the like, and each of R4 to R6 individually represents a hydrogen atom or the like. In the formula (1-3), R3 represents a hydrogen atom or the like, Rq represents a single bond or the like, and each of R5 and R6 individually represents a hydrogen atom or the like.
