Honeycomb structure, electric heating type honeycomb structure, electric heating type catalyst and exhaust gas purifying device

A honeycomb structure, comprising:

• an outer peripheral wall;
• and partition walls disposed on an inner side of the outer peripheral wall, the partition walls defining a plurality of cells, each of the plurality of cells extending from one end face to the other end face to form a flow path for a fluid,
• wherein the partition walls and the outer peripheral wall comprise ceramics, wherein the ceramics contain:
• silicon;
• and
• at least one selected from the group consisting of alumina, mullite, zirconia, cordierite, silicon carbide, silicon nitride, and aluminum nitride;
• wherein a content of silicon in the ceramics is 30% by mass or more;
• wherein the silicon contains B as a dopant;
• and
• wherein the honeycomb structure has a volume resistivity of 0.01 Ω·cm or more and 5 Ω·cm or less.
