Beschreibung
Zusammenfassung:	Provided is a method for producing a catalyst having a high raw material conversion rate and a high product selectivity as well as excellent yield of unsaturated carboxylic acid, the catalyst being used in a vapor-phase catalytic oxidation reaction for producing an unsaturated carboxylic acid such as acrylic acid or methacrolein from an unsaturated aldehyde such as acrolein or methacrolein. A method for producing a catalyst for synthesizing an unsaturated carboxylic acid, the method including a molding process of molding a powder containing each catalyst component element to produce a catalyst precursor, wherein a sulfur-containing inorganic compound is added to the powder, and the powder is molded in the molding process.
