摘要： A cylindrical honeycomb structure formed by spirally winding a strip metal flat sheet and a strip metal corrugated sheet overlapped thereon. The metal flat sheet is welded, at each turn, to the metal corrugated sheet at a plurality of axially arranged welding positions on each portion where the metal flat sheet contacts the metal corrugated sheet. Letting L be the axial length of the honeycomb structure and D be the diameter of the honeycomb structure, the maximum value L1 of distances between adjacent welding positions satisfies at least one of relationships given by L1≦/D/2 and L1≦/L/2, or the distance L2 between the outermost welding positions in the axial direction of the honeycomb structure and the outer end face of the honeycomb structure satisfies at least one of relationship given by L2≦/D/20 and L2≦/L/10.
