摘要：
The present invention relates to catalysts for producing an unsaturated carboxylic acid, containing: a catalytically active component represented by the following formula (1), in which the catalysts have a median diameter D50S (mm) 5.0 mm or more and 8.0 mm or less, and a relationship between a specific surface area A (m2/g) and the D50S (mm) is expressed by the following expression (2). (Mo)12(V)a(W)b(Cu)c(Sb)d(X)e(Y)f(Z)g(O)h (1) 8.0 ≤ D50S × A ≤ 20.0 (2)
