ABSTRACT:
A tubular honeycomb structure1comprising partition walls2which define and form a plurality of cells3each functioning as a fluid passage extending from one end face4of honeycomb structure to other end face5, wherein the areas of the sections of the individual cells3(cell sections) normal to the flow direction A of fluid are so made as to be approximately equal to each other over a given range of the center of each cell and its vicinity in the fluid flow direction A and to gradually decrease or gradually increase at each cell end of at least one end face4of honeycomb structure in the fluid flow direction A. This honeycomb structure can reduce the incoming loss and outgoing loss of a fluid such as exhaust gas or the like and can show a lower pressure loss.
