An object of the present invention is to provide a honeycomb structure in which ash can be easily discharged to the outside and pressure loss can be kept low, and the honeycomb structure of the present invention has a plurality of cells with cell walls. A honeycomb structure that is arranged in parallel in the longitudinal direction and sealed at either one end of the cells, and has a porosity of 70 to 95% and is perpendicular to the longitudinal direction of the honeycomb structure The ratio of the length in the longitudinal direction of the honeycomb structure to the diameter of the cross section is 0.2 to 0.9. |
