PROBLEM TO BE SOLVED: To provide a steel sheet pile with a laterally asymmetric joint and a manufacturing method of the steel sheet pile having excellent driving performance, joint detaching resistance and watertightness, rapidly and economically manufactured and causing no trouble at a driving site. SOLUTION: This steel sheet pile has the laterally asymmetric joint having an arm part 1c extending almost parallel with a driving normal line direction, and capable of connecting the adjoining steel sheet piles to each other with the cross-sectional shape arranged in the same direction, by the engagement of an outward joint 1a and an inward joint 1b. In this constitution, the opening part width K1 of the outward joint 1a, the opening part width K2 of the inward joint 1b, the maximum thickness Nt1 of the outward joint 1a and the maximum thickness Nt2 of the inward joint 1b are set to satisfy the relation of 0.65<=Nt1/2<=1.00 and 0.85<=Nt2/K2<=1.50 or less.
