A production process of a chemical amplification-type resist composition, which is a process for producing a chemical amplification-type composition comprising: (A) a compound capable of generating an acid upon irradiation with actinic rays or radiation; (B) a resin of which solubility in an alkali developer is changed under an action of an acid; (C) a basic compound; (D) a surfactant; and (E) a solvent, the production process comprising: preparing a solution containing the component (A); and mixing the solution containing the component (A) with the components (B) to (E), and a chemical amplification-type resist composition produced by the production process.
