Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a method of manufacturing a multiple oxide catalyst excellent in activity and selectivity with excellent reproducibility. SOLUTION: In the method of manufacturing the multiple oxide catalyst containing at least metal elements of molybdenum, bismuth and iron, sintering is performed a plurality of times and the mixing of the catalyst is performed between an interval of the sintering.
