A positive photosensitive composition comprising (A1) a compound that generates an aromatic sulfonic acid substituted with at least one fluorine atom and/or a group having at least one fluorine atom upon irradiation of an actinic ray or radiation, (B) a resin that has a monocyclic or polycyclic alicyclic hydrocarbon structure and is decomposed by the action of an acid to increase solubility in an alkali developing solution, and (C) a compound that has at least three hydroxy or substituted hydroxy groups and at least one cyclic structure or (A2) an onium salt of an alkanesulfonic acid in which the α-position of the sulfonic acid is not substituted with a fluorine atom and/or an onium salt of a carboxylic acid.
