Claim:
A ceramic honeycomb structure body which is formed by binding a plurality of porous honeycomb segments with an adhesive layer interposed between each neighboring two of the plurality of porous honeycomb, the adhesive layer being adhered to a first adhesion surface of one of the neighboring two porous honeycomb segments, and being adhered to a second adhesion surface of the other of the neighboring two porous honeycomb segments, wherein a first plurality of protrusion portions fixed to at least one of the first and second adhesion surfaces respectively of each neighboring two of the honeycomb segments are embedded in the adhesive layer, the two neighboring honeycomb segments being opposite to each other with the adhesive layer interposed therebetween; the first plurality of protrusion portions are not in contact with the other of the first and second adhesion surfaces, and the protrusion portions have substantially the same height.
