PROBLEM TO BE SOLVED: To provide a method for producing a heat-treated member by which man-hour, time and equipment can be reduced, its wear resistance (hardness) and strength can be improved, and required toughness can be secured. SOLUTION: This method for producing a heat-treated member comprises a process in which a material consisting of medium carbon boron steel containing 0.301 to 0.50 wt.% carbon is formed into a prescribed shape to form a stock, and a process in which the stock is subjected to heat treatment consisting of only quenching with tempering obviated.
