Abstract: The invention provides a valve which suppresses a continuous corrosion of a chemical compound phase such as an eutectic carbide or the like in a valve seat, and improves a corrosion resistance, an impact resistance and an erosion resistance of the valve seat. The invention disperses a chemical compound phase such as the eutectic carbide or the like crystallizing in a dendrite gap as a granular shape or a blocky shape which is equal to or less than about 100 μm, by moving a tool rotating in a crimped state by a load application to a vertical direction to a surface of the valve seat so as to carry out a friction stir processing, and forming a weld metallographic structure of a surface layer portion of the valve seat as a cubic.
