PROBLEM TO BE SOLVED: To provide a highly precise steel sheet pile which stabilizes a shape of a product, by enabling the uniform rolling of the steel sheet pile. SOLUTION: A cross section of a steel sheet pile body part except a joint part is formed in such a shape as to have at least one bent part, and the rolled steel sheet pile is formed in such a manner that the board thickness of the steel sheet pile body part in the rolling direction thereof is made almost uniform. For example, in the case of a hat-shaped steel sheet pile which is manufactured by hot caliber rolling, a board thickness tw of a web part, a board thickness tf of a flange part and a web angleαsatisfy the expression.
