A catalyst that includes molybdenum, copper, and vanadium as essential components thereof and has a ratio (X/Y) of 1.10-3.00 between the volume (X) of pores having a diameter of 25-400 μm as measured by mercury intrusion porosimetry and the volume (Y) pores having a diameter of 0.1-4 μｍ. L'invention concerne un catalyseur qui comprend du molybdène, du cuivre et du vanadium en tant que composants essentiels de celui-ci et présente un rapport (X/Y) de 1,10-3,00 entre le volume (X) de pores ayant un diamètre de 25 à 400 µm tel que mesuré par porosimétrie par intrusion de mercure et les pores de volume (Y) ayant un diamètre de 0,1 à 4 µm. モリブデン、銅及びバナジウムを必須成分として含み、水銀圧入法により測定した細孔直径が２５μｍ～４００μｍの範囲にある細孔の容積（Ｘ）と細孔直径が０．１μｍ～４μｍの範囲にある細孔の容積（Ｙ）との比（Ｘ／Ｙ）が１．１０以上３．００以下である、触媒。
