PURPOSE: A sintered alloy that enables the reducing of coefficient of friction and the sealing of pores on a surface thereof and a method of manufacturing the same are provided. CONSTITUTION: The sintered alloy comprises a sintered alloy body(1) formed by compacting material powders and then sintering the same, wherein the sintered alloy body has pores providing a porosity 2 to 35 volume %, each pore having an inlet portion having a pore inlet diameter and an inside portion having a pore inside diameter, wherein the pore inlet diameter is from about 10 to about 200 μm, and an average ratio of the pore inlet diameter to the pore inside diameter is at least about 2.0, wherein the sintered alloy body has a resin film layer(3) on at least a portion of a surface thereof. The method of manufacturing a sintered alloy comprises the steps of forming a sintered alloy body, having pores therein providing a porosity of about 2 to above 35 volume %, wherein each pore has an inlet portion having a pore inlet of about 0 to about 200 μm, and an inside portion having a pore inside diameter, wherein an average ratio of the pore inlet diameter to the pore inside diameter is at least 2.0; and forming a resin film layer comprising solid lubricant coating on at least a portion of a surface of the sintered alloy body, using solid lubricant coating. |
