Provided is a honeycomb structure (100) which comprises a plurality of passages (110a, 110b) almost parallel with each other and separated from each other by a partition wall (120). According to the present invention, an end of the passage (110a) is sealed by a sealing part (130) on an end surface (100a) of the honeycomb structure (100), and an end of the passage (110b) is sealed by the sealing part (130) on the other end surface (100b) of the honeycomb structure (100). Assuming that the number of communication holes detected when the resolution of an image of the partition wall (120) acquired through X-ray computed tomography measurement is 1.5 ㎛/pixel is X, and the number of communication holes detected when the resolution of the image is 2.5 ㎛/pixel is Y, Y/X is equal to or greater than 0.58. |
