<P>PROBLEM TO BE SOLVED: To provide a honeycomb structure which is prevented from being displaced by vibration or the like and whose strength is hardly lowered when it is accommodated in a can, and which can be easily produced, and its production process. <P>SOLUTION: The honeycomb structure 1 has: a cell structure part 20 which is constituted of partition walls 2 arranged so as to form a plurality of cells 3 penetrating in the axial direction; and an outer peripheral wall 7 arranged at the outer periphery of the cell structure part 20. The surface roughness Ra of the outer peripheral surface of the peripheral wall 7 is 1-80 μm. <P>COPYRIGHT: (C)2004,JPO |
