PROBLEM TO BE SOLVED : To provide a magnet junction body with improved corrosion resistance and mechanical strength. SOLUTION : In a magnet junction body 10 including a first magnet 2a, a second magnet 2b, and an intermediate layer 4 joining the first magnet 2a and the second magnet 2b, the first magnet 2a and the second magnet 2b are both permanent magnets each of which includes a rare earth element R, a transition metal element T, and boron B. Further, the rare earth element R includes at least a light rare earth element RL and a heavy rare earth element RH having Nd, and the transition metal element T includes Fe, Co, and Cu. Furthermore, the intermediate layer 4 includes an RL oxide phase including an oxide of the light rare earth element RL and an RL-Co-Cu phase including the light rare earth element RL, Co, and Cu.
