Zusammenfassung:	The purpose of the present invention is to clarify moisture absorption characteristics of a catalyst for acrylic acid production, ascertain a relationship between moisture content in the catalyst andperformance as a catalyst for acrylic acid production, and provide an excellent catalyst. Provided is a catalyst for acrylic acid production, which contains molybdenum and vanadium as essential activeingredients and in which the quantity of moisture contained in the catalyst is 0.01-0.53 mass%. 本发明的目的在于明确丙烯酸制造用催化剂的吸湿特性，确定催化剂的水分量与作为丙烯酸制造用催化剂的催化剂性能之间的关系，并提供优异的催化剂。一种丙烯酸制造用催化剂，其中，所述催化剂含有钼和钒作为必要活性成分，所述催化剂中含有的水分量为0.01质量％以上且0.53质量％以下。
