Abstract

A gel which contains a component of a catalyst is prepared. The gel and another gel are arranged in layers at a position which faces open ends of exhaust flow passages of a wall flow-type particulate filter. Next, a pusher is used to push and pack the gel and other gel through the open ends to the insides of the exhaust flow passages. Next, the particulate filter is made to dry to thereby make the partition walls carry the catalyst on their surfaces or in their micropores.
