<P>PROBLEM TO BE SOLVED: To provide a manufacturing method of an exhaust gas purifying filter capable of shortening a baking time to enhance productivity and capable of suppressing the occurrence of trouble at the time of baking. <P>SOLUTION: The manufacturing method of the exhaust gas purifying filter 1 constituted by providing plug parts 13 to a honeycomb structure 10 comprising cordierite and having a large number of cells 12 provided by arranging porous partition walls 11 in a honeycomb state has an extrusion molding process for a honeycomb molded body by extruding a ceramics material to mold a honeycomb molded body, a drying process for drying the honeycomb molded body, a baking process for baking the honeycomb molded body and a plugging process for arranging plugging slurry to the parts to be plugged by the plug parts 13 among the opening parts of the cells of the end surface of the honeycomb molded body before the baking process. In the first baking in the baking process, the amount of supplied oxygen into an oven is suppressed until the decomposition of the organic component contained in the honeycomb molded body is completed from starting. <P>COPYRIGHT: (C)2008,JPO&INPIT |
