Honeycomb structure, and manufacturing method of the same

A honeycomb structure comprising:

• a pillar-shaped honeycomb structure body;
• and a pair of electrode members disposed on the side of a side face of the honeycomb structure body,
• wherein the honeycomb structure body has porous partition walls and a circumferential wall disposed at an outermost circumference,
• in the honeycomb structure body, the partition walls define a plurality of cells extending from a first end face of the honeycomb structure body to a second end face thereof,
• the honeycomb structure body is made of a material containing silicon carbide, and the pair of electrode members contains silicon and boron,
• at least a part of each electrode member is made of a composite material including silicon containing 100 to 10000 ppm of boron in silicon, as a main component, and at least one of a metal boride and a boride,
• in the composite material, a volume ratio of the silicon containing 100 to 10000 ppm of the boron in the composite material is 70 volume % or more, and an electric resistivity of the electrode members made of the composite material is from 20 μΩcm to 0.1 Ωcm.
