Abstract

There is disclosed a honeycomb structure which is a catalyst carrier, also functions as a heater when a voltage is applied thereto, can inhibit an unevenness of a temperature distribution, and is excellent in thermal shock resistance. The honeycomb structure includes a honeycomb structure body 4 and a pair of electrode members 21 disposed on a side surface 5 of the honeycomb structure body 4, each of the pair of electrode members 21 is shaped in the form of a band extending in a cell extending direction of the honeycomb structure body 4, and in a cross section perpendicular to the extending direction of cells 2, one electrode member 21 is disposed on a side opposite to the other electrode member 21 via a center of the honeycomb structure body 4, one or more slits 6 opened in the side surface 5 are formed in the honeycomb structure body 4, the honeycomb structure body 4 has a charging material 7 charged into the at least one slit 6, the charging material 7 contains aggregates and a neck material, and a ratio (α2/α1) of a thermal expansion coefficient α2 of the charging material 7 to a thermal expansion coefficient α1 of the honeycomb structure body 4 is from 0.6 to 1.5.
