PROBLEM TO BE SOLVED: To manufacture a metallic member having an alloy layer of dispersing hard compound particles therein, on the surface, without using a jointing method such as welding. SOLUTION: This method for manufacturing the metallic member comprises sealing the powder of the alloy containing a compound in a tubular container, and hot-isostatic-forming and/or hot-extruding the container in the state, to thereby divide the compound and metallically combine powders with each other. In the above step, the metallic member may be inserted into the container, or alternatively when the metallic member is tubular, the container is formed of the material of the metallic member. Then, the container is machined into the metallic member having the alloy layer with the hard compound particles dispersed therein, on the surface. The metallic member having the alloy layer with the hard compound particles dispersed therein, on the surface, is manufactured without using the jointing method such as welding.
