PROBLEM TO BE SOLVED : To provide a method for producing an anisotropic magnet ribbon capable of crystallizing an amorphous ribbon and capable of orienting an axis of easy magnetization in a direction vertical to a ribbon surface. SOLUTION : In a method for producing an anisotropic magnet ribbon, an amorphous ribbon is irradiated with a microwave to be heated to 550-850°C, the amorphous ribbon having a composition represented by : RxFe100-x-y-w-zCoyBwMz (where R represents one or more selected from rare earth elements, M represents one or more selected from among Ga, Al, Cu, Au, Ag, Zn, In and Mn and inevitable impurity elements, and 5≤x≤20, 0≤y≤8, 4≤w≤6.5 and 0≤z≤2 are satisfied).
