PROBLEM TO BE SOLVED: To provide a ceramic honeycomb structure stored in a metallic vessel through a grip member and capable of preventing the reduction of a grip force by the grip member even if the metallic vessel swells due to high temperature exhaust gas, preventing it from leaving and moving due to the vibration of an engine, and reducing the wear due to the friction with the metallic vessel. SOLUTION: Recessed and projecting parts are formed on an outer peripheral face of the ceramic honeycomb structure. Preferably, the maximum height of the recessed and projecting parts is 5 to 500μm.
