PROBLEM TO BE SOLVED: To provide a rotary machine with an anticorrosive coating applied thereon, in which a plated layer constituting the anticorrosive coating can be uniformly deposited with suppressed pin holes and is prevented from being peeled thereby providing enhanced durability to the anticorrosive coating, and enhanced corrosion resistance, reliability and efficiency to the rotary machine. SOLUTION: The rotary machine with the anticorrosive coating applied thereon in which the anticorrosive coating is applied on a part through which gas flows and with which the gas directly contacts, is characterized in that the anticorrosive coating has a first Ni-P plated layer deposited in an electroless plating on a surface of a base material of the above part, and a second Ni-P plated layer deposited in an electroless plating on the first Ni-P plated layer, and in that opening parts of the pin holes on the surface of the first Ni-P plated layer are filled with fluororesin or polyimide.
