PROBLEM TO BE SOLVED: To provide a method for manufacturing an iron-based sintered alloy member superior in dimensional accuracy, strengths and sliding properties. SOLUTION: The method for manufacturing the iron-based sintered alloy member having a composition consisting of 0.5-7% Cu, 0.1-0.98% C, 0.02-0.3% oxygen if necessary 0.0025-1.05% Mn and/or 0.001-0.7% Zn, and the balance Fe with inevitable impurities, comprises blending an Fe powder, a graphite powder and a Cu alloy powder for a base powder, then mixing, molding and sintering them, wherein the Cu alloy powder to be blended for the base powder has a composition consisting of 1-10% Fe, 0.2-1% oxygen, if necessary, 0.2-10% Zn and/or 0.5-15% Mn, and the balance Cu with inevitable impurities.
