There is disclosed a honeycomb structure which is useful as a trapping filter for an exhaust gas, above all a diesel particulate filter (DPF) for trapping particulate matters (particulates) in an exhaust gas from a diesel engine and in which internal and external temperature rises are uniformed during use and during regeneration and in which there are effectively prevented generation of defects such as cracks due to a thermal stress and generation of an adverse influence on a carried catalyst. A honeycomb structure 1 includes: a bonded honeycomb segment article 10 in which bond surfaces of a plurality of honeycomb segments 2 are integrally bonded to one another via bonding material layers 9 ; and an outer peripheral coating layer 4 which coats an outer peripheral surface of the bonded honeycomb segment article 10 . The honeycomb structure has a structure in which a plurality of cells 5 forming fluid channels are arranged in parallel with one another in a central axis direction. The honeycomb segments 2 are bonded via the bonding material layers (partial bonding material layers) 9 disposed only in predetermined portions of the honeycomb segments 2.
