PROBLEM TO BE SOLVED: To provide a production method for a long-length rolled wire rod of a magnesium based alloy provided with excellent strength and toughness. SOLUTION: This method comprises a stage where a magnesium based alloy stock comprising, by weight, 0.1 to 12.0% Al is prepared, and a stage where the stock is subjected to rolling by caliber rolls so as to be a wire shape. In the rolling, provided that the rolling temperature is defined as T<SB>r</SB>(°C), the rolling degree in one pass as R<SB>n</SB>(%), and the content of Al as Al (wt.%), the following relations are satisfied: R<SB>n</SB>≤T<SB>r</SB>/10-5×Al/3+12.5 in the case of T<SB>r</SB>≥200, and 0≤R<SB>n</SB>≤T<SB>r</SB>/10-5×Al/3+2.5 in the case of T<SB>r</SB><200.
