[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. |
