Claim:
1. An actinic-ray- or radiation-sensitive resin composition comprising: a resin (P) containing a repeating unit (A) that when exposed to actinic rays or radiation, is decomposed to thereby generate an acid and a repeating unit (B) with a structure that when acted on by an acid, is decomposed to thereby increase its solubility in an alkali developer, and a compound (U) structured so that when the composition is formed into a film, the compound is unevenly distributed in a vertical direction of the film; wherein the resin (P) further comprises a repeating unit (C) containing an alkali-soluble group represented by the general formula (C-I): wherein, each of R X Ar n is an integer of 1 to 4, and wherein the repeating unit (A) is represented by any of the following general formulae (I): wherein in general formula (I), each of R X each of, X L L Ar Z wherein, each of Z each of Rz A wherein, in general formula (CT1), each of R in general formula (CT2), each of R
