    摘要: A honeycomb structure which is useful as a capturing filter for exhaust gas, especially as a DPF for capturing particulate substances in exhaust gas from a diesel engine, and which can prevent effectively occurrence of such defects as cracking due to thermal stress during use and regeneration. The honeycomb structure comprises a honeycomb segment bonded body where a plurality of honeycomb segments are bonded integrally at the mutual bonding faces through a bonding material layers, and an outer circumferential coat layer covering the outer circumferential surface of the honeycomb segment bonded body, and has such a structure that a plurality of cells becoming the channels of fluid are arranged in parallel to each other in the direction of central axis. The honeycomb structure is characterized in that a bonded cross portion where two or more bonding material layers intersect has a thermal capacity relatively lower than that at other bonded portions, i.e. the bonding material layers other than the bonded cross portion.
