Disclosed is an exhaust gas purifying honeycomb filter that is excellent in heat resistance and thermal shock resistance, has high thermal decomposition resistance, and has high mechanical strength, and can be stably used at fluctuating high temperatures, and a method for manufacturing the same. A honeycomb filter for removing solid fine particles mainly composed of carbon in exhaust gas, the material of the honeycomb filter being a composition formula: Mg x Al 2 (1-x) Ti (1 + x) O 5 (wherein A mixture containing Mg-containing compound, Al-containing compound and Ti-containing compound at a metal component ratio similar to that of Mg, Al and Ti in aluminum magnesium titanate represented by 0 <x <1), or Contains 100 parts by mass of the mixture in terms of oxide and 1 to 10 parts by mass of alkali feldspar represented by the composition formula: (Na y K 1-y ) AlSi 3 O 8 (where 0 ≦ y ≦ 1) It is the aluminum magnesium titanate sintered compact which baked the molded object of the mixture to be performed at 1000-1700 degreeC. |
