Abstract:
A tubular honeycomb structure 1 comprising partition walls 2 which define and form a plurality of cells 3 each functioning as a fluid passage extending from one end face 4 of honeycomb structure to other end face 5, wherein the areas of the sections of the individual cells 3 (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 face 4 of 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.
