PROBLEM TO BE SOLVED: To fill respective reaction tubes of a fixed bed type multi-tubular reactor with a catalyst furthermore simply with well-suppressed unevenness of pressure loss in the respective reaction tubes after the packing of the catalyst. SOLUTION: The method is a method for filling respective reaction tubes of a fixed bed type multi-tubular reactor with a produced catalyst for unsaturated aldehyde production or a produced catalyst for an unsaturated carboxylic acid production a plurality of times and involves (1) weighing the catalyst for each reaction tube in a manner that the packing weight of the catalyst to be packed in a reaction tube is in a range of 99 to 101% of the average value of the respective packing weights of the catalyst to be packed in the respective reaction tubes and (2) filling the respective reaction tubes with the catalyst weighed in the step (1) in a manner that the speed of filling a reaction tube with the catalyst weighed in the step (1) is in a range of 80 to 120% to the average value of the respective speeds of filling the respective reaction tubes with the catalyst in weights measured respectively in the step (1).
