Abstract
A photosensitive resin composition includes a cationically polymerizable compound, a photoacid generating agent having an anion portion and a cation portion, and a salt having a cation portion having either one of a quaternary ammonium structure and a quaternary phosphonium structure and an anion portion, wherein the anion portion of the salt is exchanged with the anion portion of a first acid derived from the anion portion of the photoacid generating agent to form a second acid having acid strength that is lower than acid strength of the first acid.
