A honeycomb-like structure 100 having a plurality of flow paths 110a and 110b is described, which are divided by dividing walls 120 and are substantially parallel to each other; and one end of the flow path 110a is plugged by a plug part 130 on an end surface 100a of the honeycomb structure 100, and one end of the flow path 110b is plugged by a plug part 130 on the other surface end 100b of the honeycomb structure 100, where in an image of the dividing walls 120 obtained by the X-ray CT measurement, when the number of communication holes detected when the image resolution is 1.5 µm / pixel is defined as X, and the number of communication holes detected when the image resolution is 2.5 µm / pixel, is defined as Y, Y / X is 0.58 or greater. |
