Provided is a high performance permanent magnet. The permanent magnet is equipped with a sintered body provided with: a composition represented by a composition formula of RpFeqMrCutCo100-p-q-r-t and including carbon of 50 mass ppm to 1500 mass ppm, inclusive; and a metallic structure including a main phase having a Th2Zn17-type crystal phase and a subphase having a carbide phase of the element M in the composition formula. In an x-ray diffraction pattern obtained by an x-ray diffraction measurement of the sintered body, the ratio (I2/I1) of the maximum intensity I2 of the diffraction peak positioned at an angle 2[theta] in the range of 37.5 degrees to 38.5 degrees, inclusive, to the maximum intensity I1 of the diffraction peak positioned at an angle 2[theta] in the range of 32.5 degrees to 33.5 degrees, inclusive, is greater than 25 and at most 80.
