Provided is a solid acid catalyst for use in oxidation of a substrate in the coexistence of oxygen and ozone (solid acid catalyst for oxygen-ozone-coexisting oxidation). The solid acid catalyst enables oxidation of the substrate with a high conversion. This solid acid catalyst for oxygen-ozone-coexisting oxidation is a solid acid catalyst for use in an oxidation reaction to oxidize a substrate (A) in the coexistence of oxygen and ozone. The solid acid catalyst includes a transition metal in the form of an elementary substance, a compound, or an ion, and a support supporting the transition metal. The support includes, at least in its surface, a strong acid or super strong acid having a Hammett acidity function (H.sub.0) of −9 or less. The support is preferably a pellet or particle made of a fluorinated sulfonic acid resin, or a support including a solid and a layer of a fluorinated sulfonic acid resin disposed on the solid.
