An object of the present invention is to provide a honeycomb structured body that makes it possible to support a catalyst supporting carrier or a catalyst so as to prevent the increase in pressure loss depending on the rate of pores having a pore diameter of 10 µm or less to the entire pores or the porosity, and also to sufficiently exert catalyst functions, and the honeycomb structuredbody of the present invention is a honeycomb structured body in which a plurality of porous ceramic members are combined with one another through an adhesive layer, each of the porous ceramic members having a plurality of cells which are allowed to penetrate in a longitudinal direction with a wall portion therebetween and either one end of which is sealed, with a catalyst supporting layer being adhered to the wall portion, wherein, supposing that the rate of the pore volume of pores having a pore diameter of 10 µm or less to the entire pore volume of the porous ceramic member is X 1 (%), the porosity is Y 1 (%) and the weight of the catalyst supporting layer is Z 1 (g/l), these X 1 , Y 1 and Z 1 are allowedto satis fy the following expressions (1) and (2) : X 1 ‰ 20 - Z 1 / 10 and Y 1 ‰¥ 35 + 7 �¢ Z 1 / 40 (where 20 ‰ Z 1 ‰ 150).
