PROBLEM TO BE SOLVED: To provide a powdery mixture with which a high strength sintered component can be produced. SOLUTION: By weight% to the total content of a powdery mixture of alloy steel powder, Ni powder, Cu powder and graphite powder, 0.5 to 4 wt% Ni and 0.5 to 5 wt% Mo are added so as to partially be alloyed into the alloy steel powder, further, 1 to 5 wt% Ni powder as Ni, 0.5 to 4 wt% Cu powder as Cu and 0.2 to 0.9 wt% graphite powder as C are added, a 0.3 to 1 pts.wt. lubricant is added to 100 pts.wt. of the powdery mixture of the alloy steel powder, Ni powder, Cu powder and graphite powder, and the balance is composed of Fe with inevitable impurities.
