摘要： A honeycomb structure comprising a plurality of honeycomb members (21) having a number of distribution holes (11) partitioned by partition walls (20), the plurality of honeycomb members (21) being joined along surfaces (22) (joining surfaces) substantially parallel to the direction of flow passage of the distribution holes (11) by joining members (25) of substantially the same material as the honeycomb members (21), the honeycomb members (21) being integrated into the honeycomb structure. In this honeycomb structure, the joining surfaces (22) in the honeycomb members (21) each include at least an end connected to a flow passageway inlet end surface outer periphery (15) and/or flow passageway outlet end surface outer periphery (17) and have a unjoining portion (12). This honeycomb structure is superior in durability, having no possibility of producing cracks due to thermal stress during use.

摘要： A catalyst element which comprises a carrier containing a cordierite binding phase and an aggregate phase dispersed in the binding phase, and, carried thereon, a catalyst material containing an alkali metal and/or an alkaline earth metal; and a method for manufacturing the catalyst element which comprises a step (I) of molding a raw material of a carrier containing a binding material component for forming a cordierite binding phase (1) and an aggregate material component for forming an aggregate phase (2), to prepare a molded product, a step (II) of firing the molded product, to form a carrier containing a cordierite binding phase and an aggregate phase dispersed in the binding phase, and a step (III) of allowing the carrier to carry a catalyst material containing an alkali metal and/or an alkaline earth metal. The catalyst element allows the suppression of the reaction of an alkali metal or the like with a catalyst carrier, which leads to the prevention of deterioration of the carrier and lowering of performance capabilities of the catalyst.
