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.
The method of manufacturing the gas cleaning filter includes processes of: molding a plurality of segment moldings 10g comprising a plurality of cells partitioned by partitions extended in a single axial direction and molded by extrusion molding of unbaked ceramic material becoming a porous body by baking; sticking the plurality of segment moldings with unbaked connection bodies 11g disposed among the plurality of segment moldings, formed with ceramic material and having axial length L shorter than the axial length N of the segment moldings; and baking the stuck segment moldings and unbaked connection bodies to integrate the segment moldings with connection bodies by sintering.
