There is disclosed a honeycomb structure capable of using as a catalyst carrier and also suitably functions as a heater by applying a voltage, and where a bonding layer to bond honeycomb segments together is hard to break and an electrical resistance value is hard to rise. The honeycomb structure includes a honeycomb segment bonded body 4 in which a plurality of honeycomb segments 6 are bonded together by a bonding layer 7, and a pair of electrode members 21 disposed on a side surface 5 of the honeycomb segment bonded body 4, each of the pair of electrode members 21 is formed into a band shape extending in an extending direction of cells 2 of the honeycomb segments 6, and in a cross section perpendicular to the extending direction of the cells 2, one electrode member 21 is disposed on an opposite side across the center of the honeycomb segment bonded body 4 to another electrode member 21, and in at least a part of the bonding layer 7, inorganic fibers made of ²-SiC and a metal silicide are included in a porous body where particles of silicon carbide are bound with silicon as a binding material in a state where pores are held among the particles. |
