    摘要： A honeycomb structure which effectively prevents generation of defects such as cracks by thermal stress during use and regeneration and has excellent durability is provided. In a honeycomb structure 1 in which honeycomb segments 2 having part of the whole shape of the honeycomb structure are bonded integrally by means of a bonding material 9, the honeycomb structure includes inner partition walls 6 having a number of first pores and arranged so as to form a plurality of cells 5 serving as flow channels for exhaust gas between two end faces through processing of the outer circumference of the bonded body into a predetermined shape, outer circumferential wall 8 having a number of second pores and arranged so as to surround the inner partition walls 6, and internal partition wall internal partition walls of the segments contacting to the outer circumferential wall) 11 having a number of third pores and contacting with a processed outer circumferential surface becoming an outermost circumference through processing of an outer circumferential portion. A filling composition containing particles of a particle size capable of coming into the second pores and a binder capable of binding particles and the insides of the second pores of the outer circumferential wall 8 and/or binding particles is disposed inside the second pores of the outer circumferential wall 8, and/or a filling composition containing particles of a particle size capable of coming into the third pores and a binder capable of binding particles and the insides of the third pores of the internal partition walls of the segments contacting to the outer circumferential wall 11 and/or binding particles is disposed inside the third pores of the outer circumferential wall 4.
