PROBLEM TO BE SOLVED: To provide an anticorrosive steel pipe pile which ensures such qualities as extreme long durability and superior impact resistance by the use of a high-corrosion-resistant metal coating and can be manufactured at low costs at high production efficiency, and to provide a manufacturing method for the anticorrosive steel pipe pile. SOLUTION: A resin coating layer 3 is formed on the outer periphery of a steel pipe pile body 2, and a high-corrosion-resistant metal plate 51 is rolled and fixed around the outer surface of the resin coating layer 3 via an adhesive layer 4 to form a metal coating layer 5. This allows forming the resin coating layer 3 into a layer having a given thickness, so that a resin used for the resin coating layer 3 is saved to prevent an increase in material costs while ensuring anticorrosive durability. Because the metal coating layer 5 is formed by winding the high-corrosion-resistant metal plate 51, a shift between the adhesive layer 4 and the high-corrosion-resistant metal plate 51 is prevented and alignment of the high-corrosion-resistant metal plate 51 is facilitated to offer better workability in disposing the high-corrosion-resistant metal plate 51, thus improve production efficiency.
