<P>PROBLEM TO BE SOLVED: To provide a honeycomb structure used as a honeycomb catalytic body to which a wall flow structure is applied so that a fluid such as exhaust gas passes through a partition wall twice or more, or as a catalyst carrier of the honeycomb catalytic body in which a pore characteristic and the like are appropriately adjusted as the catalytic body. <P>SOLUTION: In the honeycomb structure 11 including porous partition walls 4 arranged to form a plurality of cells 3 which communicate between two end surfaces and having a lot of pores; and sealed portions 10 arranged to seal at least a part of the plurality of cells 3 at any position in a length direction of the cells, an average maximum image distance of the partition walls 4 is larger than 40μm, and the sealed portions 10 are arranged so that at least a part of a fluid which has entered the cells 3 from one end face passes through the partition wall 4 twice or more, and is then discharged from the other end portion. <P>COPYRIGHT: (C)2008,JPO&INPIT |
