To provide a method for manufacturing a sintered member having high dimentional precision and capable of reducing a dimensional intra-lot variation caused by the lot of raw material powder without significantly changing the conventional process and management level.

This manufacturing method comprises at least a raw material powder preparing step of blending raw iron powder and carbon powder to prepare raw material powder, a molding step of molding the raw material powder to form green compact, a sintering step of sintering the green compact to form a sintered body, and a heat treatment step of performing the heat treatment of the sintered body. The correlation between the dimensional changes and the carbon content in the green compact sintering step and the correlation between the dimensional changes and the carbon content in the green compact heat treatment step are positive on one side, and negative on the other side. A first of the raw material powder of this characteristic is ferrous alloy powder containing, by weight, at least 2-4% Cr and a second of the raw powder is mixed powder containing 0.7-1.3% copper powder for the total raw powder of 100%.
