METHOD OF MANUFACTURING FILTER, AND FILTER
To suppress increase of a pressure loss while maintaining purification efficiency of an exhaust gas.SOLUTION: A method of manufacturing a filter includes: a process (a first catalyst slurry-attaching process S110) of attaching a catalyst slurry containing at least a catalyst metal and water onto a surface of a filter wall composing at least one cell of a wall flow-type carrier having a plurality of cells partitioned by the filter wall; a process (a first particle-attaching process S120) of attaching a particle of a water-absorbing polymer onto a surface of the catalyst slurry; a process (a swelling process S150) of swelling the particle with water contained in the catalyst slurry into a predetermined size; and a process (a calcining process S170) of calcining the carrier attached with the catalyst slurry and the particle.SELECTED DRAWING: Figure 2
【課題】排気ガスの浄化効率を維持しつつ、圧力損失の増加を抑制する。【解決手段】フィルタの製造方法は、フィルタ壁で区画された複数のセルを有するウォールフロー型の担体における少なくとも１のセルを構成するフィルタ壁の表面に、触媒金属および水を少なくとも含む触媒スラリーを付着させる工程（第１触媒スラリー付着工程Ｓ１１０）と、吸水性ポリマーの粒子を触媒スラリーの表面に付着させる工程（第１粒子付着工程Ｓ１２０）と、触媒スラリーに含まれる水で粒子を所定の大きさまで膨張させる工程（膨張工程Ｓ１５０）と、触媒スラリーおよび粒子が付着された担体を焼成する工程（焼成工程Ｓ１７０）と、を含む。【選択図】図２
