Claim 0:
1. An actinic ray-sensitive or radiation-sensitive resin composition comprising:
a resin whose solubility in a developer is changed by the action of an acid; and
a photoacid generator represented by General Formula (b1),
wherein the photoacid generator represented by General Formula (b1) is a compound that generates an acid having a pka of 1.0 or less upon irradiation with actinic rays or radiation,, in General Formula (b1),
R1 represents a substituent,
R2 represents a group forming a having at least one heteroatom other than S+, which may have a substituent, together with S+, and
an aromatic ring group is not disposed at at least one of a position bonded to S+ in R1 and two positions bonded to S+ in R2,
provided that the substituent represented by R1 has an anionic group which is a group having a sulfonate anion group or the group represented by R2 has an anionic group which is a group having a sulfonate anion group.
