Summary: | To provide a VOC removal catalyst that can be easily produced, has excellent VOC removal efficiency, and can efficiently remove VOCs even at low temperature, a production method thereof, and a VOC removal method.SOLUTION: A production method of a VOC removal catalyst includes a step 1 for mixing a raw material containing a metal element M and a gelatinizer to obtain a gelatinous precursor and a step 2 for burning a product material obtained by mixing the gelatinous precursor and an oxidizer containing Mn, to obtain a complex oxide containing Mn and the metal element M. The metal element M is at least one selected from the group consisting of transition metals, rare-earth elements, and noble metal elements.SELECTED DRAWING: None
