Zusammenfassung:	[Problem] To provide a honeycomb structure in which the generation of cracks, which is caused by the thermal stress when repeatedly burning and removing collected fine particles, is inhibited as a consequence of the honeycomb structure exhibiting high thermal shock resistance. To also provide a gas treatment device provided with said honeycomb structure. [Solution] A honeycomb structure (1) provided with an outer wall (2), multiple partitioning walls (3) disposed on the inside of the outer wall (2), and a sealing material (4), wherein: spaces surrounded by the outer wall (2) and the partitioning walls (3) or by the partitioning walls (3) function as circulation paths (5) for a fluid; the flow inlets or the flow outlets of the circulation paths (5) are sealed by means of the sealing material (4); the partitioning walls (3) are formed from a sintered body which contains aluminum titanate as the main component; and the X-ray strength of the (101) surface of the partitioning wall crystal, which is the crystal of aluminum titanate, is higher than the X-ray strength of the (230) surface in a first cross-section which is cut along the circulation paths (5) so that the circulation paths (5) become divided. [Problème] Produire une structure en nid d'abeilles dans laquelle la génération de craquelures, qui est causée par la contrainte thermique lors de la combustion et du retrait répétés de particules fines collectées, est inhibée en conséquence du fait que la structure en nid d'abeilles présente une résistance aux chocs thermiques élevée. L'invention concerne en outre un dispositif de traitement de gaz pourvu de ladite structure en nid d'abeilles. [Solution] La présente invention concerne une structure en nid d'abeilles (1) pourvue d'une paroi externe (2), de parois de séparation multiples (3) disposées sur l'intérieur de la paroi externe (2), et d'un matériau d'étanchéité (4), dans laquelle : les espaces entourés par la paroi externe (2) et les parois de séparation (3) ou par les parois de séparation (3) fonctionnent comme des trajets de circulation (5) pour un fluide; des entrées d'écoulement ou des sorties d'écoulement des trajets de circulation (5) sont scellées au moyen du matériau d'étanchéité (4); les parois de séparation (3) sont formées d'un corps fritté qui contient du titanate d'aluminium en tant que composant principal; et la résistance aux rayons X de la surface (101) du cristal de paroi de séparation, qui est le cristal de titanate d'aluminium, est pl
