Patent ID: 8034299

Claim:
A catalyst carrier comprising: a ceramic block having two open faces and an outer peripheral surface, the ceramic block having a plurality of cells divided by a cell wall and extending between the two open faces, wherein the ceramic block has a plurality of honeycomb units combined by interposing an adhesive layer, the honeycomb units including an outer-peripheral-side honeycomb unit and a center-side honeycomb unit combined to form an outer peripheral part and a center part, respectively, of the ceramic block, wherein the outer-peripheral-side honeycomb unit and the center-side honeycomb unit contain inorganic particles and at least one of inorganic fibers and whiskers, wherein the outer-peripheral-side honeycomb unit has an outer peripheral cell wall forming an outer peripheral surface of the outer-peripheral-side honeycomb unit, the outer peripheral cell wall including an outermost peripheral cell wall forming a part of the outer peripheral surface of the ceramic block, and wherein the outer-peripheral-side honeycomb unit includes an outermost peripheral cell positioned on an outer peripheral side of the ceramic block, the outermost peripheral cell including corner parts, and at least one corner part among the corner parts in contact with the outermost peripheral cell wall of the outer-peripheral-side honeycomb unit has a curved surface.
