Claim:
1. An actinic-ray- or radiation-sensitive resin composition, comprising: a resin containing a repeating unit containing a group that is decomposed when acted on by an acid to thereby produce an alcoholic hydroxyl group, and a compound that generates an acid of pKa≧−1.5 when exposed to actinic rays or radiation, wherein the group that is decomposed when acted on by an acid to thereby produce an alcoholic hydroxyl group is expressed by at least one selected from the group consisting of general formulae (II-1) to (II-4) below, the resin contains no fluorine atom, and the acid of pKa≧−1.5 generated by the compound is at least one member selected from the group consisting of a carboxylic acid, an imidic acid, and a methide acid, in which R R each of R
