Abstract
There is provided a honeycomb structural body with a lower-than-conventional heat capacity and excellent durability. A honeycomb structural body (1) having partition walls composed mainly of cordierite arranged in a honeycomb fashion is provided with fortified section (2) with a higher strength than the general section (19) at one end or both ends (11) in the direction of length of the partition walls (10). The fortified section (2) is given improved strength by having increased density with respect to the general section.
