    摘要: A resist composition is provided that yields fine resolution, and improved levels of line edge roughness and depth of focus. This composition includes a resin component (A) that undergoes a change in alkali solubility under the action of acid, and an acid generator component (B) that generates acid on exposure, wherein the component (A) is a resin with a weight average molecular weight of no more than 8,000 containing structural units (a) derived from a (meth)acrylate ester, and the component (B) includes at least one sulfonium compound represented by a general formula (b-1) or a general formula (b-2) shown below.
