Provided is a sealed honeycomb structure that can suppress an increase in pressure loss and can improve the durability well. Honeycomb structure 4 having porous partitions 1 defining an inlet cell 2a and an outlet cell 2b extending from an inlet end face to an outlet end face 12, and an outlet side sealing part 5b. And at least one corner portion 21a provided with an inlet side sealing portion 5a, wherein at least one outlet cell 2b intersects a partition wall 1 having a cross section perpendicular to the direction in which the cell 2 extends. Is a reinforcement cell 22 having a reinforcement part 6 formed therein for reinforcing the outflow cell 2b, and the inlet cell 2a is a cross section in which the partition walls 1 of a cross section perpendicular to the direction in which the cell 2 extends cross each other. The reinforcement cell 23 is not provided with the reinforcement part 6 in the corner part 21, and the reinforcement part 6 of the reinforcement cell 22 is formed from the outflow end surface 12 of the honeycomb structure 4. Sealed honeycomb structure (100) formed in a portion of the extending direction. |
