A method of producing the honeycomb structure includes steps of extruding a ceramic batch to form a honeycomb structure having a ridge in the form of a shape extending at least one part of the honeycomb structure in cross-section, and removing at least one part of the ridge in directions of through-apertures of the honeycomb structure to form a notch. With the arrangement of the honeycomb structure, it is possible to prevent any lifting of the honeycomb structure in directions of through-apertures of the structure and rotation of the structure about its axis relative to a converter can without closing any ends of through-apertures.
