Summary:The honeycomb structure has a plurality of partition walls and cells surrounded by the partition walls, and pores formed inside partition walls between adjacent cells communicating with each other. The plurality of the cells have open cells which are penetrated in the axial direction and plugged cells having one upstream end which face the exhaust gas flow plugged by the plug portion. The honeycomb structure has a first region which does not carry the catalyst on the partition walls and a second region which carries the catalyst on the partition walls.
