Claim Text:
1. An actinic-ray- or radiation-sensitive resin composition comprising: (A) a resin to be decomposed to increase its solubility in an alkali developer when acted on by an acid, and (B) a monovalent ionic compound represented by the general formula (1-1) below, where A represents a sulfur atom or an iodine atom, R Ar each independently represents an aromatic ring group, X each independently represents a bivalent connecting group, R at least two groups selected from X and two R provided that to the nitrogen atom (N) in the general formula (1-1), at least one group is directly bonded, the group being selected from a cycloaliphatic group, an aromatic hydrocarbon group, a heterocyclic hydrocarbon group and a chain aliphatic group whose moiety adjacent to the nitrogen atom is a tertiary or quaternary carbon atom, and an electron withdrawing group selected from a carbonyl group, a sulfonyl group, a cyano group and a halogen atom is not directly bonded, when A is a sulfur atom, n is an integer of 1 to 3, and m is an integer satisfying the relationship m+n=3, when A is an iodine atom, n is an integer of 1 or 2, and m is an integer satisfying the relationship m+n=2, o is an integer of 1 to 10, and Y
