Claim:
An actinic-ray- or radiation-sensitive resin composition comprising a compound (A) that when exposed to actinic rays or radiation, generates any of the acids of general formula (II) below and a resin (B) whose rate of dissolution into an alkali developer is increased by the action of an acid, wherein A represents a nitrogen atom or a carbon atom, R 1 represents a monovalent organic group containing a fluorine atom in a ratio satisfying the relationship (mass of all fluorine atoms contained)/(mass of all atoms contained)≦0.35, and R 2 represents a group containing an electron withdrawing group, provided that when A is a nitrogen atom, n+m=2, n=1 or 2, and m=0 or 1, and that when A is a carbon atom, n+m=3, n is an integer of 1 to 3, and m is an integer of 0 to 2, provided that when n is 2 or greater, the two or more R 1 s may be identical to or different from each other, and R 1 s may be bonded to each other to thereby form a ring, and that when R 1 s are bonded to each other to thereby form a ring, the above ratio of fluorine atom contained in R 1 refers to the ratio of fluorine atom contained in a bivalent group formed by the bonding of two R 1 s, and provided that when m is 1 or greater, R 1 and R 2 may be bonded to each other to thereby form a ring, and that in this instance, the above ratio of fluorine atom contained in R 1 refers to the ratio of fluorine atom contained in a bivalent group formed by the mutual bonding of R 1 and R 2 .
