<P>PROBLEM TO BE SOLVED: To provide an exhaust gas cleaning filter which can stably remove a deleterious substance such as a particulate matter (PM) in an exhaust gas at a low temperature and for a long period of time, and also, is highly heat-resistant. <P>SOLUTION: This exhaust gas cleaning filter 1 is installed in an exhaust path for the exhaust gas which is discharged from an internal combustion engine and cleans the exhaust gas. The exhaust gas cleaning filter 1 comprises a honeycomb-type or foam-type filter base 2 and, being supported thereon, an exhaust gas cleaning catalyst 4 prepared by calcining a mixture of zeolite and an alkali metal element source and/or an alkaline earth metal element source, or sodalite at not less than 600°C. <P>COPYRIGHT: (C)2010,JPO&INPIT |
