摘要：
Provided is a method for manufacturing an exhaust gas purification catalyst device, the method comprising: (A) placing a catalyst coating layer-forming coating liquid on the upper end surface of a honeycomb substrate having a plurality of cell flow paths partitioned by cell walls in a coating liquid placing station; (B) transferring the substrate, on which the coating liquid has been placed, from the coating liquid placing station to a suction station; and (C) suctioning the substrate, on which the coating liquid has been placed, from the lower end surface in the suction station to coat the cell walls of the substrate with the coating liquid, wherein the suction station comprises two or more suction devices, and step (B) comprises (B1) transferring the substrate, on which the coating liquid has been placed, from the coating liquid placing station to a branch station, and (B2) transferring the substrate, on which the coating liquid has been placed, to an empty suction device among the suction devices of the branch station.
