PROBLEM TO BE SOLVED: To provide a method for efficiently producing (meth)acrylic acid from propane or isobutane. SOLUTION: A catalyst which is obtained by subjecting an aqueous solution or a slurry containing molybdenum, vanadium, tellurium and iron to a hydrothermal synthesis at >=110 deg.C and <300 deg.C, separating the slurry by a filtration after the reaction to give a solid, drying the solid and baking the dried solid in an inert gas atmosphere is used. |
