<P>PROBLEM TO BE SOLVED: To provide a method of manufacturing a gas cleaning filter that is used at high temperature, and hardly causes cracks even when the temperature distribution in a filter base body is uneven. <P>SOLUTION: The method of manufacturing a gas cleaning filter includes processes of: extrusion-molding a molding 25g, using a ceramic material becoming a porous body by baking, having a plurality of segment parts 20 comprising a plurality of cells extended in the axial direction Z, and connection parts 21 crosslinking adjacent segment parts vertically in the axial direction, and connecting the adjacent segment parts in the axial direction over the whole length, with a width d of the connection part shorter than the length W of the side of the segment part, ; cutting the connection parts by cutting from one end in the axial direction toward the other end without reaching the other end, and obtaining the molding 25g including an integrated filter part Cf with the adjacent segment parts connected by an uncut connection part, and a separated filter part Sf having no connection part between the adjacent segment parts; and baking the molding subjected to the cutting process. <P>COPYRIGHT: (C)2011,JPO&INPIT |
