Abstract

A ceramic honeycomb body has a plurality of through holes defined by partition walls so as to be separated from each other, and fins are integrally formed with selected partition walls so as to extend into the through holes surrounded by such selected partition walls, whereby the cross-sectional area of the through hole is selectively reduced by the fins thus provided.
