Abstract
A process for producing a ceramic honeycomb structural body, comprises the steps of placing a green ceramic honeycomb structural body on a ceramic plate, and then firing the green ceramic honeycomb structural body. The green ceramic honeycomb structural body is placed on the ceramic plate in the state that a cell-opened end face contacts the ceramic plate. The ceramic plate is composed mainly of heat-resistive inorganic fibers, and has a bulk density of not less than 1.00 g/cm.sup.3.
