Zusammenfassung:	PURPOSE:To obtain a porous ceramic material having high porosity and large pore diameter by baking a composition containing SiO2, CaO and Al23 at specific ratios wherein the diameter of CaO particles is larger than that of SiO2 particles. CONSTITUTION:A porous ceramic material is produced by baking a composition containing SiO2, CaO and Al2O3. The composition contains 70-88wt.% of SiO2, 5-23wt.% of CaO and 5-15 wt.% of Al2O3 and the particle size of the CaO in the composition is larger than that of the SiO2 particles. Preferably, the particle diameter of CaO is >=5 times as large as that of the SiO2 particles, the diameter of the SiO2 particle is =10mum.
