Abstract
A honeycomb structure includes a plurality of honeycomb segments each having a polygonal cross section with an adhesive agent interposed between each two honeycomb segments, the plurality of honeycomb segments each having a plurality of channels which are partitioned from one another by porous partition walls, the plurality of channels penetrating through the honeycomb segment in a uniaxial direction. The plurality of honeycomb segments are arrayed in a way that adhesive agent-applied surfaces and adhesive agent-unapplied surfaces respectively of the plurality of honeycomb segments are arranged alternately along bonded lines each joining bonded surfaces respectively of abutting honeycomb segments. In each of the honeycomb segments, an adhesive agent is applied to at least one side surface, and the honeycomb segments and at least one honeycomb segment, in each of which the adhesive agent is applied to no side surface.
