Abstract
An actinic ray-sensitive or radiation-sensitive resin composition contains a compound represented by General Formula (1). In General Formula (1), X represents a sulfur atom or an iodine atom. m represents 1 or 2, in a case where X is a sulfur atom, m is 2, and in a case where X is an iodine atom, m is 1. R's each independently represent an alkyl group or alkenyl group which may include a heteroatom, an aromatic heterocyclic group, or an aromatic hydrocarbon ring group. Further, in a case where m is 2, two R's may be bonded to each other to form a ring. Rrepresents a divalent linking group. Rrepresents a divalent linking group having no aromatic group. Yrepresents an anionic moiety. The pKa of the compound represented by General Formula (1) as Yis protonated is −2.0 to 1.5.
