Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an unsaturated carboxylic acid production process by using a catalyst having both a high catalyst capability and a strong mechanical strength.SOLUTION: Provided is an unsaturated carboxylic acid production process in which a supported catalyst obtained by feeding a catalytically active component containing a liquid binder component and molybdenum and vanadium, and/or a precursor thereof, into a rolling granulator and granulating at a relative centrifugal acceleration of 0.5 G or more and 30 G or less, is used. 【課題】高い触媒性能と強い機械的強度を兼ねそなえた触媒を使用した不飽和カルボン酸の製造法を提供する。【解決手段】液状のバインダー成分とモリブデン及びバナジウムを含有する触媒活性成分および／またはその前駆体を転動造粒機に供給し、相対遠心加速度が０．５Ｇ以上３０Ｇ以下で造粒して得られる担持触媒を使用する。【選択図】なし
