摘要： PROBLEM TO BE SOLVED: To provide a steel pipe pile capable of suppressing penetration resistance to improve workability and preventing the structure thereof from becoming complicated and the manufacturing cost thereof from increasing, a manufacturing cost thereof, and a construction method of the steel pipe pile.SOLUTION: A diameter reduced part 12 is formed at the tip of a steel pipe pile 1. Therefore, the interior of the steel pipe pile 1 is prevented from being clogged so that penetration resistance can be reduced, and the area of a pile tip end is increased by the projection area of a taper face part 123 of the diameter reduced part 12 so that the end bearing capacity of the steel pipe pile 1 can be increased. Furthermore, a tip opening end fringe 122 of the diameter reduced part 12 is inclined with respect to a penetration direction so that the inclination of the steel pipe pile 1 can be corrected and a straightly advancing property thereof can be improved by a leading-edge part 124 of the tip opening end fringe 122 surely excavating a high bearing layer side even in case of penetration into the ground of an inclined bearing layer.
