Abstract: A honeycomb structure includes a honeycomb segment bonded member including; a plurality of prismatic columnar shaped honeycomb segments; and a bonding layer bonding the segments, wherein one honeycomb segment has a bulge on one side face, extending in an axial direction, another honeycomb segment has a recess on one side face, extending in the axial direction, the one honeycomb segment and the another are disposed adjacent and bonded to each other via the bonding layer with the bulge inserted in the recess, length of the bulge is smaller than length of the one side face of the one honeycomb segment, length of the recess is smaller than length of the one side face of the another honeycomb segment, a base part of the bulge is defined with a bent side face, an angle between an imaginary bottom face and the bent side face of the bulge being 60° or more.

Abstract: The honeycomb structure includes a pillar-shaped honeycomb structure body that includes a porous partition wall. When the thickness (μm) of the partition wall is defined as T1 and, among pores formed in the partition wall, the value of an average pore diameter (μm) of specific pores whose pore diameters measured by a mercury press-in method are 20 to 100 μm is defined as D(20 to 100), T1/D(20 to 100) that is a value obtained by dividing T1 by D(20 to 100) is not less than 2.4, a ratio of a pore volume of the specific pores to an overall pore volume of the partition wall is 5 to 45%, and a ratio of a pore volume of large pores whose pore diameters are not less than 100 μm to the overall pore volume of the partition wall is not more than 5%.

Abstract: A honeycomb structure includes honeycomb segments, bonding layers and a circumferential wall. The bonding layers include bottomed-hollow voids which extend toward an internal side in an axial direction from an end face of the honeycomb structure and which are formed at at least one of intersections, and a ratio of a depth of each void in the axial direction to a length of each honeycomb segment in the axial direction is 5% or more.

Abstract: A honeycomb structure comprising a pillar-shaped honeycomb structure body, wherein the honeycomb structure body has at least one missing part, the average size of the missing part is such that the radial length on the end face of the honeycomb structure body is 0.8 to 8.0 mm, the perimeter along the rim of the end face of the honeycomb structure body is 0.8 to 41.0 mm, and the axial length in the extending direction of the cells of the honeycomb structure body is 0.1 to 32.0 mm, and a percentage of a ratio of total area of the missing part is 1.40% or less.
