Claim Text:
1. A honeycomb structure in which a plurality of honeycomb segments are integrally bonded via a bonding material, each of the honeycomb segments having a first end surface, a second end surface, porous partition walls to define and form a plurality of cells extending from the first end surface to the second end surface, and an outer peripheral surface connecting the first end surface to the second end surface, wherein as to each of the honeycomb segments other than the honeycomb segments positioned in the outermost periphery of the honeycomb structure among the plurality of honeycomb segments, the first end surface and the second end surface of the honeycomb segment have rectangular shapes having the same dimensions, and are in a positional relation in which extending directions of long sides of the respective end surfaces are perpendicular to each other when the first end surface is viewed from a direction perpendicular thereto, (X−Y)/2 is from 0.2 to 7 mm, where X is a length of each long side of each of the first end surface and the second end surface having the same dimensions, and Y is a length of each short side of each of the first end surface and the second end surface having the same dimensions, the outer peripheral surface comprises four side surfaces, the four side surfaces are constituted of a pair of first tapered side surfaces including two side surfaces opposing each other so that a distance between the side surfaces becomes narrow from the side of the first end surface toward the side of the second end surface, and a pair of second tapered side surfaces including two side surfaces opposing, each other so that a distance between the side surfaces becomes narrow from the second end surface side toward the first end surface side, and in two directions perpendicular to each other on each end surface of the honeycomb structure, the respective first end surfaces of a pair of adjacent honeycomb segments are directed opposite to each other, and the extending direction of the long side of the first end surface of one honeycomb segment in the pair of adjacent honeycomb segments is parallel to an extending direction of the short side of the second end surface of the other honeycomb segment in the pair of adjacent honeycomb segments.
