Claim 0:
1. An actinic ray-sensitive or radiation-sensitive resin composition comprising:
a resin having a repeating unit having a group in which a phenolic hydroxyl group is protected with an acid-leaving group and a repeating unit having a lactone structure;
a first photoacid generator that generates an acid having a pKa of −2.00 to 2.00, in which in a case where the acid thus generated is a carboxylic acid, a pKa of the carboxylic acid is −2.00 or more and less than 1.00;
a second photoacid generator that generates a carboxylic acid having a pKa of 1.00 or more,
wherein the second photoacid generator is a photoacid generator that generates benzenecarboxylic acid having a substituent which is a fluorine atom or a group including a fluorine atom, and
the first photoacid generator is formed of an anion and a cation, and the anion has a cyclic acetal structure.
