Provided is a method for manufacturing a honeycomb structure such that it is possible to prevent cracks caused by contact between honeycomb units that constitute the honeycomb structure when manufacturing a honeycomb structure in which multiple honeycomb units are assembled. This method for manufacturing a honeycomb structure manufactures a honeycomb structure in which multiple honeycomb units are assembled, the honeycomb units comprising silicon carbide provided with multiple cells which are to be exhaust gas channels and porous cell partition walls that define the cells. This method for manufacturing a honeycomb structure comprises: an extrusion molding step of extrusion molding a ceramic feedstock including silicon carbide to form a honeycomb molding; a degreasing step of degreasing the honeycomb molding to form a honeycomb degreased body; a firing step of firing the honeycomb degreased body to form a monolithic honeycomb fired body; a cutting step of cutting the monolithic honeycomb fired body in a direction parallel to the longitudinal direction to form multiple honeycomb units; and an assembling step of assembling the multiple honeycomb units via adhesive layers to form a honeycomb structure. The honeycomb molding formed in the extrusion molding step has, in a cross section vertical to the longitudinal direction, cutting areas that are to be cut in the cutting step and functional areas other than the cutting areas. |
