Abstract
A honeycomb structure including: a honeycomb structure body having porous partition walls which are disposed to surround a plurality of cells and a circumferential wall, wherein the partition walls are provided with protrusions, at least one of the plurality of cells includes a specific cell configured so that the protrusions protrude into the cell from the respective partition walls, and the specific cell is provided with a porous material made of the same material as the partition walls in a range of 5 to 50% including an intersection with respect to a pentagonal area which is formed by connecting the intersection when two partition walls configuring the peripheral edge of the specific cell extend and two points of bottom parts and top parts, respectively, of the respective protrusions disposed on the two partition walls, in the cross section orthogonal to the extending direction of the cells.
