Right and left end flanges are formed at opposite sides of the rolled steel sheet pile. Joints are formed at edges of the right and left end flanges. Cross-sections of the joints are point-symmetric or line-symmetric, wherein the end flange and the joint are disposed so that a center of point-symmetry of a pair of interfitted joints is located on or near a centerline of the end flange in the thickness direction. Furthermore, the joint has a protrusion for preventing rotation near the border between the joint and the end flange portion.
