PROBLEM TO BE SOLVED: To provide a steel sheet pile capable of forming a thick continuous wall as in the case of Z-steel sheet pile, having a section modulus larger than that of the Z-steel sheet pile as a single steel sheet pile to reduce deformation in driving, capable of being manufactured by hot rolling only, and easily handled in the state of the single steel sheet pile. SOLUTION: The steel sheet pile 1 has a chevron cross section with the intersection A of a wall surface sheet 2 and a wall surface joining sheet 3 as a crest point. Larsen joints 4, 5 in the steel sheet pile 1 comprise claws having claw bottom parts 4b, 5b positioned parallel to the wall surface sheet 2 and extending in the direction of separation from the crest point A and hook parts 4c, 5c, respectively. At the crest point A of a chevron shape there is a flat part 6 on the crest point side which is made parallel to a floor F when the steel sheet pile 1 is horizontally placed on the flat floor F with the crest point A placed upward and is formed at the position and the width W of a range including the center G1 of the cross section when projected downward in a vertical direction.
