<p>With the recent yearly increase in cell density, use of the same slurry as a conventional one for forcibly depositing a solid, e.g., alumina for supporting, on the surface of cell walls has come to arouse a trouble that the resultant coat layer is thick and cell clogging is more apt to occur. When a slurry whose viscosity has been reduced by reducing the binder amount is used, the slurry which has flowed into cells is discharged without leaving a solid adherent to the surface of the cell walls. Namely, it is difficult to secure a desired solid deposition amount. A honeycomb structure (1) for slurry coating is provided which is made of a porous object, wherein the surface (5) of cell walls formed in the structure has fine pores (7) dispersedly formed therein and having a pore diameter (r) of 2 µm or smaller. Preferably, the total volume (v) of the fine pores (7) is 0-0.17 ml, excluding 0 ml, per g of the structure.</p> |
