PROBLEM TO BE SOLVED: To provide a steel pipe pile which can easily and surely realize the water-sealing effect to a continuous wall to be executed underground, and can be pressed into the ground in a rotating manner, and a construction method for a continuous wall of steel pipe piles. SOLUTION: Steel pipe piles 1 and 10 construct a continuous wall by joining steel pipes 2 and 2 adjacent to each other via joining members 4 and 11 to be engaged with engagement plates 3 and 3, and comprise the steel pipe 2 and the engagement plates 3, 3 joined with an outer circumferential surface of the steel pipe 2. The steel pipe piles 1 and 10 can be pressed into the ground in an easily rotating manner since the engagement plate 3 which is not projected much is provided on the outer circumferential surface of the steel pipe 2. Since the steel pipe piles 1, 1, 10 and 10 can surely be connected using the engagement plate 3 and the joining members 4 and 11, the continuous wall high in strength can be constructed, and the water sealing effect is realized between the steel pipe piles 1....
