    摘要: An objective of the present invention is to provide a rare earth metal-based permanent magnet with improved adhesion properties. A rare earth metal-based permanent magnet of the present invention as a means for achieving the objective has a laminated plating film, and is characterized in that the plating film comprises as an outermost surface layer a SnCu alloy plating film having a film thickness in a range from 0.1 μm to 2 μm, the composition of the SnCu alloy plating film is 35 mass % or more but less than 55 mass % of Sn and the rest being Cu, and a base plating film having two or more layers including at least a Ni plating film and a Cu plating film which are formed as the lower layer under the SnCu alloy plating film, and among the base plating film, the Ni plating film is located just below the SnCu alloy plating film. A joined structure fabricated using the rare earth metal-based permanent magnet of the present invention exhibits favorable initial adhesion strength when combined with a silicone-based adhesive, and is less deteriorated in adhesion strength even after a moisture resistance test.
