PROBLEM TO BE SOLVED: To provide a manufacturing method of a catalyst for purifying an exhaust gas which can decrease the variation in the coating quantities of slurries produced in respective carriers, and also can decrease in excess slurries. SOLUTION: In such a state that the lower end surface 30a of the carrier 30 comes close to a liquid level of the slurries, while a suction is carried out from the upper part side of the carrier 30, the lower end surface 30a moves to the slurry side, by which the lower end surface 30a turns to a state arranged on the lower side than the liquid level of the slurry, at the same time the lower end surface 30a follows to the liquid surface of the falling slurry, and the slurry is suctioned in the carrier 30. Subsequently, the carrier 30 is turned upside down, and at the same time pressurized blowing is carried out to the carrier 30 from the upper end to disperse uniformly a catalytic material entirely in the carrier 30. Thereafter, by drying and calcining the carrier 30, the catalytic material is supported in the carrier 30. COPYRIGHT: (C)2010,JPO&INPIT
