ABSTRACT:
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 Li2O, Na2O, K2O, MgO, CaO, SrO and BaO and containing at least two alkali metal oxides selected from the group consisting of Li2O, Na2O and K2O as an essential component, at least 3 mol % of at least one of ZrO2and TiO2as a total amount, and SiO2and incidental impurities as the balance.
