Abstract
The honeycomb structure includes a pillar-shaped honeycomb structure body having porous partition wallsdefining a plurality of cells and a circumferential wall, and a pair of electrode members disposed on the side of a side surface of the honeycomb structure body. The pair of electrode members contain metal silicon and boron, at least a part of the electrode member is made of a composite material including, as a main component, silicon containing 100 to 10000 ppm of boron in silicon. In the composite material which is comprised the electrode member, a volume ratio of the silicon containing 100 to 10000 ppm of the boron in the composite material is 70 volume % or more. An electric resistivity of the electrode member made of the composite material is from 20 μΩcm to 0.1 Ωcm.
