The present invention provides: a production process for a catalyst for synthesis of an unsaturated aldehyde and/or an unsaturated carboxylic acid, which production process is suitable for producing the catalyst with good reproducibility, wherein the catalyst is excellent in activity, selectivity, and physical strength; this catalyst; and a production process for the unsaturated aldehyde and/or the unsaturated carboxylic acid by using this catalyst. The production process for the catalyst comprises the steps of: carrying out heat treatment of an aqueous solution or slurry of a starting material to thus prepare a catalyst precursor P1, wherein the starting material includes molybdenum, bismuth, and iron as essential components; thereafter adding and mixing a binder into the P1 to thus prepare a catalyst precursor P2; and molding and then calcining the P2, thereby producing the catalyst for synthesis of the unsaturated aldehyde and/or the unsaturated carboxylic acid; with the production process being characterized by involving an ignition loss ratio of the catalyst precursor P1 in the range of 10 to 40 mass % (excluding 40 mass %). |
