The present invention provides a honeycomb structure that can be suitably used for a particulate collecting filter such as a diesel particulate filter (DPF) and the like, when used in a particulate collecting filter, it is possible to detect the amount of particulate accumulation easily and with high accuracy. A honeycomb structure 1 in which a plurality of cells serving as gas passages are partitioned by porous partition walls, each having two or more electrodes 2 therein. |
