Patent ID: 7666488

Claim:
A honeycomb structure comprising: a honeycomb segment assembly to be obtained by bonding 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, wherein each of the plurality of honeycomb segments includes adhesive agent-applied side surfaces to which the adhesive agent is applied, and adhesive agent-unapplied side surfaces to which the adhesive agent is not applied, the adhesive agent-applied side surfaces and the adhesive agent-unapplied side surfaces face each other, in the honeycomb structure, each of the plurality of honeycomb segments is bonded by the adhesive agent interposed between the adhesive agent-applied side surfaces and the adhesive agent-unapplied side surfaces, the adhesive agent-applied side having a stronger segment surface than the adhesive-agent unapplied side, and the adhesive agent-applied surfaces and the adhesive agent-unapplied surfaces are arranged alternately along bonded surfaces consisting of the adhesive agent.
