Abstract
Provided is a honeycomb structure in which as compared with partition walls of an end face side portion of all inlet of a fluid, partition walls of an end face side portion of an outlet of the fluid satisfy at least one of conditions of (1) a heat conductivity being relatively high, (2) a heat capacity being relatively large, (3) a bending strength being relatively high and (4) a porosity being relatively low. In this honeycomb structure, the melting or thermal shock breakdown of the partition walls does not easily occur, and the structure is suitably used as a DPF.
