wherein in the first end region (11, 21, 31, 41), easy magnetization axes (10b, 20b, 30b, 40b) of the magnet material particles included in the first end region are oriented in such a manner as to be directed along a path which enters the inside of the sintered body from the second planar surface and extends toward the first planar surface; and in the second end region (12, 22, 32, 42), easy magnetization axes (10c, 20c, 30c, 40c) of the magnet material particles included in the second end region are oriented in such a manner as to be directed along a path which enters the inside of the sintered body from the first planar surface and extends toward the second planar surface, characterized in that the easy magnetization axes (10b, 30b) of the magnet material particles included in the first end region (11, 31) are oriented in parallel alignment in such a manner as to be directed in a direction approximately orthogonal to the second planar surface, and in that the easy magnetization axes (10c, 30c) of the magnet material particles included in the second end region (12, 32) are oriented in parallel alignment in such a manner as to be directed in a direction approximately orthogonal to the second planar surface.
