Abstract
A resist composition which generates an acid when the resist composition is exposed and whose solubility with respect to a developing liquid varies by action of the acid. The resist composition contains a base material component whose solubility with respect to a developing liquid is varied by action of an acid and an acid generator component that generates an acid when the acid generator component is exposed. The base material component contains a polymer compound that includes a constituent represented by a general formula (a-1) described in the specification and a constituent (a2) represented by a general formula (a-2) described in the specification. The acid generator component contains a compound represented by a general formula (b1) described in the specification.
