PROBLEM TO BE SOLVED: To provide a Cu-based sintered alloy having high thermal conductivity and excellent abrasion resistance capable of being used for a valve guide or a valve seat of an engine having high thermal load by down sizing or direct injection high supercharging.SOLUTION: A Cu-based sintered alloy having high thermal conductivity and excellent abrasion resistance by dispersing 3 to 40 mass% of an Fe-based alloy having Vickers hardness of 300 HV0.1 or more in a Cu matrix or a Cu matrix consisting of a Cu-based alloy mainly containing Cu.SELECTED DRAWING: Figure 2
