Claim Text:
1. An actinic ray-sensitive or radiation-sensitive resin composition comprising: (A) a compound capable of generating an acid by irradiation of actinic rays or radiation; and (B) a resin of which solubility in an alkali developer increases by being decomposed by the action of an acid, wherein the actinic ray-sensitive or radiation-sensitive resin composition contains at least one type of a compound represented by the following General Formula (A-I) and at least one type of a compound represented by the following General Formula (A-II) as the compound (A), wherein in General Formula (A-I), R wherein in General Formula (A-III), each Ar independently represents an aryl group or a heteroaryl group, wherein in General Formula (A-II), R wherein in General Formula (A-IV), X represents —CR wherein in General Formulae (A-VI-1) to (A-VI-3), R in General Formula (A-V), R wherein the ratio of the compound represented by (A-I) and the compound represented by (A-II) is 30/70 to 10/90 in terms of the compound represented by (A-I)/the compound represented by (A-II).
