Abstract
There is disclosed a honeycomb structure comprising a plurality of honeycomb segments (), bonded into one piece, having an outer peripheral wall (), cell walls () disposed inside the outer peripheral wall, and a large number of cells () partitioned by the cell walls and passing through an axial direction. The honeycomb structure () comprises the honeycomb segment () in which the cell walls () have an angle in a range of 25 to 65 degrees to a straight line along an outermost point of the outer peripheral wall () adjacent to another honeycomb segment, in a vertical section to an X-axis direction of the honeycomb structure (). The honeycomb structure including the honeycomb segment can be used in a filter for trapping particulate in an exhaust gas of an internal combustion engine, boiler, etc. and can be superior in resistance to cracks by a thermal stress.
