A sintered alloy has an overall composition consisting of, by mass %, 13.05 to 29.62% of Cr, 6.09 to 23.70% of Ni, 0.44 to 2.96% of Si, 0.2 to 1.0% of P, 0.6 to 3.0% of C, and the balance of Fe and inevitable impurities; a metallic structure in which carbides are precipitated and uniformly dispersed in an iron alloy matrix having dispersed pores; and a density of 6.8 to 7.4 Mg/m3. The carbides include specific carbides having maximum diameter of 1 to 10 μm and area ratio of 90% or more with respect to the total carbides.
