Abstract
A support for an electric heating type catalyst comprises: a honeycomb structure having partition walls that define a plurality of cells, each of cells extending from one end face to other end face to form a fluid path for a fluid; and a pair of electrode layers formed on a side surface of the honeycomb structure, the pair of electrode layers being arranged so as to face each other across a center of the honeycomb structure. The pair of electrode layers is electrically connected to the honeycomb structure. The honeycomb structure side of each of the electrode layers comprises a portion having a thermal expansion coefficient lower than that of the honeycomb structure.
