A metal fiber media exhibiting superior durability, mechanical strength, and heat transfer efficiency, a filter for an exhaust gas purifier using the same as a filter member, and a method for manufacturing the filter are disclosed. The metal filter media includes a metal fiber mat made of longitudinally-aligned metal fiber yarns each including a bundle of 20 to 500 uniformly-oriented metal fibers and having a length of 0.45 to 0.6 m per 1 g, and a torsion of 1 to 9 turns/m such that the metal fiber mat has a porosity of 30 to 95%, and supports respectively attached to upper and lower surfaces of the metal fiber mat, the supports having a porosity of 5 to 95%. Since the metal fiber media exhibits excellent durability and mechanical strength, no crack is generated in the metal fiber medial due to external impact. Accordingly, there is no possibility of damage. Since the metal fiber media has excellent heat transfer efficiency, uniform heat transfer is achieved during regeneration of the filter. Accordingly, there is no damage of the filter caused by local heating. It is also possible to prevent the material of the filter from being melted. Excellent workability and particulate matter collection efficiency are obtained.
