Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a magnet filter capable of efficiently increasing an attraction amount of foreign matter composed of magnetic powder such as metal abrasion powder without causing a size increase of external dimensions and a weight increase.SOLUTION: The magnet filter 1 comprises a ferrite injection-molded article, which is mounted in a case 50 in an engine or in a transmission, for a vehicle, for attracting and removing metal abrasion powder contained in working oil in the case 50, and the external form thereof has a flat shape having a frame part 10 and a center part 20 provided via a hollow gap part 30 on an inner side of the frame part 10, the center part 20 has thickness dimension larger than the frame part 10, and a magnetization direction in a thickness direction of the center part 20 and the frame part 10. By raising permeance moduli of the center part 20 and the frame part 10, an attraction amount of metal abrasion powder contained in the working oil in the case 50 can be effectively increased.
