Abstract

PURPOSE: To provide the packing material which consists of porous calcium phosphate having a communicated pore type porous structure and is capable of efficiently adsorbing and removing nicotine, tarry substances and other noxious substances in tobacco smoke. CONSTITUTION: This packing material consists of a porous calcium phosphate which has a porous structure having communicated pores with each other and is obtained by for example, adding an organic synthetic resin to calcium phosphate, mixing the resulting material with a forming aid to obtain a mixture, forming this mixture into a formed body and thereafter, dewaxing and burning the formed body. By using the objective packing material, the characteristic tastiness of tabacco and feeling caused at the time of smoking tobacco, are not adversely affected at all. Further, as the porous structure having communicated pores with each other, a structure that has a large number of independent spherical pores each of which has a 5 to 600μm pore size and which are communicated with each other through capillary tubes each having a 0.5 to 5μm diameter, is preferred.
