[PROBLEMS] To solve the contradictory problem that it is difficult to satisfy both high temperature rise performance and high heat capacity at the same time, and to install in front of a filter that collects particulate matter (PM) discharged from a diesel engine Thus, a honeycomb structure capable of smoothly completing regeneration of PM collected by the filter and efficiently purifying exhaust gas is provided. In a honeycomb structure in which a plurality of cells (2) communicating in parallel between two end faces (S1, S2) are formed by a plurality of partition walls (1), the plurality of partition walls (1) are made of ceramics, and 2 It is comprised from the partition 1a, 1b which has the thickness more than a seed | species.
