| 20120003420 | HONEYCOMB STRUCTURE BODY AND METHOD OF PRODUCING THE SAME - A honeycomb structure body has a honeycomb base body and a pair of electrodes composed of conductive ceramic layers and intermediate layers. The honeycomb base body made of porous ceramics containing SiC is comprised of a cell formation part and an outer peripheral part. The outer peripheral part covers the cell formation part. Each electrode is comprised of a conductive ceramic layer and an intermediate layer. The conductive ceramic layers containing SiC, Si and C are formed at two opposite positions on the outer peripheral part observed from a diameter direction. The intermediate layers containing SiC, Si and C are formed in the outer peripheral part at the parts which face the conductive ceramic layers. The honeycomb structure body satisfies a relationship of 0.5≦t/T≦1, where “t” indicates the thickness of the intermediate layer and “T” indicates the thickness of the outer peripheral part. | 01-05-2012 |
