A ceramic honeycomb structural body to be used in an automobile monolith catalyst converter in which the ceramic honeycomb structural body having numerous parallel channels are clamped by annular supporting members perpendicular to axis of said channels has such a structure that end surfaces of the ceramic honeycomb structural body are more strongly clamped at an inner circumferential portion of the above described annular supporting members than at the outer circumferential portion of said annular supporting members. Such a ceramic honeycomb structural body is stably held in the catalyst converter without forming break at the peripheral portion of the end surface of the honeycomb structural body. |
