Patent ID: 7731774

Claim:
A method of manufacturing a honeycomb structured body, comprising: combining a plurality of porous ceramic members with one another through an adhesive layer to form a ceramic block, wherein each porous ceramic member has a plurality of cells placed parallel to each other in a longitudinal direction of the porous ceramic member with a wall portion therebetween and either end of the cell is sealed; obtaining a first pore volume of pores in the porous ceramic member having a pore diameter of 10 μm or less; obtaining an entire pore volume of the porous ceramic member; obtaining a ratio X 1 (%) by dividing the first pore volume with the entire pore volume; obtaining a porosity Y 1 (%) of the porous ceramic member; applying a catalyst supporting layer on the porous ceramic member at a weight of Z 1 (g/l), wherein the values of X 1 , Y 1 , and Z 1 satisfy the following expressions: X 1 ≦20− Z 1 /10, Y 1 ≧35+7 Z 1 /40, and about 20≦Z 1 ≦about 150.
