<P>PROBLEM TO BE SOLVED: To provide a prior-to-drying pretreatment method for obtaining a honeycomb filter which reduces time required for drying a honeycomb filter to which a catalyst solution sticks, the honeycomb filter being free from the increase of pressure loss since its micropores are not covered and filled up by a catalyst, carrying a plurality of catalyst components which are homogeneously carried on it, and having a large catalyst-carrying area, so as to solve the problem that more time is required when a catalyst is carried on a three-dimensional structure body, and the pressure loss after the catalyst is carried on it greatly increases and the catalyst is not homogeneously carried on due to the movement of catalyst components in a catalyst solution; and also provide a method for manufacturing the honeycomb filter and a catalyst-carried exhausted gas purification filter obtained by said manufacturing method. <P>SOLUTION: In order to prevent a catalyst solution 9 from covering and filling the micropores 8 of a three-dimensional structure body, the micropores 8 are degassed by subjecting the three-dimensional structure body to vacuum processing or the like. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
