In an embodiment, a permanent magnet includes a composition of RpFeqZrrMsCutCo100-p-q-r-s-t (R: rare-earth element, M: at least one element selected from Ti and Hf, 10≦̸p≦̸15, 24≦̸q≦̸40.5, 1.5≦̸r≦̸4.5, 0≦̸s≦̸3, 1.5≦̸r+s≦̸4.5, and 0.8≦̸t≦̸13.5 (atomic %)). The permanent magnet has a texture including a main phase which is formed of a Th2Zn17 type crystal phase, and a grain boundary phase which has a crystal phase having a Zr concentration of from 4 atomic % or more to 35 atomic % or less.
