PROBLEM TO BE SOLVED : To provide a production method of rare earth magnet alloy ribbon capable of forming a ribbon-shaped rare earth magnet alloy stably by controlling a production parameter when producing a rare earth magnet alloy ribbon by quick chilling coagulation.SOLUTION : A model for estimating thickness H of an alloy ribbon is used in consideration of wetness of molten alloy on a cooling roll surface, and on a chart on which the thickness H of the alloy ribbon is plotted to roll peripheral speed u, a production parameter during quick chilling coagulation is selected so as to enter a predetermined area capable of achieving steady wetness.
