Abstract: A method for producing highly pure p-toluic acid by a simple solid-liquid separation operation using as a raw material a substance inducible from a biomass resource and suitable for fermentation production by a microorganism is disclosed. The method for producing p-toluic acid includes: a dehydration reaction step of dehydrating Compound(s) (1)-(4), which are substances inducible from biomass resources and suitable for fermentation production by microorganisms; and a solid-liquid separation step of recovering a solid produced by this dehydration reaction by a simple solid-liquid separation operation.
