Abstract:
1. A resist composition comprising: a resin (A) containing any of repeating units (a) of general formulae (I-a) and (I-b) below and any of repeating units (b) of general formula (II) below but containing no repeating unit in which an alcoholic hydroxyl group is introduced, wherein the resin (A) further contains a repeating unit (c) different from the repeating units (b), the repeating units (b) and the repeating unit (c) contain a group that when acted on by an acid, is decomposed, the repeating unit (c) is expressed by general formula (IV) below, and the resin (A) has a molecular weight dispersity of 1.5 to 2.0, and a photoacid generator that when exposed to actinic rays or radiation, generates an acid, which resist composition comprises at least any of compounds (B) of general formula (III-a) below, as the photoacid generator, in which R each of R
