This device provides a honeycomb structure in which stress concentration on a flat plate in the area of weld with a corrugated plate is avoided in the outer side area of the honeycomb structure, for example, the first and second layers from the outside thereof, whereby cracks and exfoliation of the flat plate are avoided in the area of the weld and the core is also protected from slipping out. In honeycomb structure 5, corrugated plate 3 and flat plate 1 are disposed alternately and welded to form a wound block. In the range of at least not less than two layers from the outside in the honeycomb structure 5, two sheets of flat plate 1 are used in a pair so that they overlap without welding therebetween. When honeycomb structure 5 is used in an environment wherein thermal cycles of heating and cooling are repeated, the outer side thereof is always cooled by open air, while the inner side is not cooled, as a result of which a difference between the amount of thermal expansion and contraction due to the temperature difference occurs and stress is generated. However, this stress is absorbed by two overlapped sheets of flat plate 1.

A honeycomb structure having a wound configuration comprising: a strip of metallic corrugated plate having a plurality of folds forming corrugations; first continuous and second continuous separate flat metallic sheets in overlapping relation with respect to each other, wherein said first and second separate flat metallic sheets are not welded to each other; said corrugated plate welded to at least one of said first and second separate flat metallic sheets; wherein the first and second separate flat metallic sheets in overlapping relation provide for reduced stresses in said honeycomb structure, thereby reducing excessive stresses which could result in failure within said honeycomb structure.
