PROBLEM TO BE SOLVED : To provide a magnet alloy having high residual magnetic flux density and coercive force, and adequate fluidity of the molten metal, workability, and corrosion resistance, while being related to the magnet alloy with high corrosion resistance, the manufacturing method therefor, and medical equipment, jewellery, electromechanical devices and the like, using the alloy. SOLUTION : The magnet alloy with high corrosion resistance is characterized by including, by atomic percentage, 30-58% Pt, elements in the IIa group, fluorine compounds of elements in the IIa group, one or more of Co, Ni, Cu, Mn, Ag, Zr, Hf, Si, V, Nb, Ta, Mo, W, Al, Ti, Sn, Ru, Os, Re, Ge, Au, Pd, Rh, Ir, rare earth elements, B, C, and N, and the balance Fe; and having the residual magnetic flux density of 3, 000 gauss or higher and the coercive force of 300 oersted or higher.
