Abstract

In order to provide a valve seat which is made of an iron base sintered alloy having excellent abrasion resistance and machinability and which is usable in a diesel engine accommodating an output increase the present invention comprises: using an intermetallic compound having a Vickers hardness (Hv) of 800 to 1200; and adjusting the contents of C and P in the composition of an iron base sintered valve seat to 1.2 to 1.6 mass% and 0.80 to 1.35 mass% respectively.
