A ceramic porous body is provided which uses a binder made of a glass that has excellent acid resistance and alkali resistance and which can be used for a long period of time as a filtration filter. The ceramic porous body is formed from ceramic particles that are bonded using a glass binder comprising 5 to 20 mol % of a plurality of metal oxides, selected from the group consisting of Li<SUB>2</SUB>O, Na<SUB>2</SUB>O, K<SUB>2</SUB>O, MgO, CaO, SrO and BaO and containing at least two alkali metal oxides selected from the group consisting of Li<SUB>2</SUB>O, Na<SUB>2</SUB>O and K<SUB>2</SUB>O as an essential component, at least 3 mol % of at least one of ZrO<SUB>2 </SUB>and TiO<SUB>2 </SUB>as a total amount, and SiO<SUB>2 </SUB>and incidental impurities as the balance. |
