wherein the photoacid generator represented by General Formula (b1) is a compound represented by General Formula (ZI-3) or a compound represented by General Formula (ZI-4),, in General Formula (ZI-3),
R1c to R5c each independently represent a hydrogen atom, an alkyl group, a cycloalkyl group, an aryl group, an alkoxy group, an aryloxy group, an alkoxycarbonyl group, an alkylcarbonyloxy group, a cycloalkylcarbonyloxy group, a halogen atom, a hydroxyl group, a nitro group, an alkylthio group, an arylthio group, or an anionic group,
R6c and R7c each independently represent a hydrogen atom, an alkyl group, a cycloalkyl group, a halogen atom, a cyano group, an aryl group, or an anionic group, and
R2 represents a group forming a heterocycle having at least one heteroatom other than S+, which may have a substituent, together with S+,
provided that any one of R1c, . . . , or R7c is an anionic group which is a group having a sulfonate anion group, or R2 is a group having an anionic group which is a group having a sulfonate anion group,, in General Formula (ZI-4),
l represents an integer of 0 to 2,
r represents an integer of 0 to 8,
R13 represents a group having a hydrogen atom, a fluorine atom, a hydroxyl group, an alkyl group, an alkoxy group, an alkoxycarbonyl group, a cycloalkyl group, or an anionic group,
R14 represents a hydroxyl group, an alkyl group, an alkoxy group, an alkoxycarbonyl group, an alkylcarbonyl group, an alkylsulfonyl group, a cycloalkylsulfonyl group, a group having a cycloalkyl group, or an anionic group,
R2 represents a group forming a heterocycle 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 the two positions bonded to S+ in R2,
provided that any one of R13 and any one of R14's which may be present in a plural number are each an anionic group which is a group having a sulfonate anion group, or R2 is a group having an anionic group which is a group having a sulfonate anion group.
