To provide a steel sheet pile suitably used for reinforcing a river bank that may be electrolytically corroded, and a steel sheet pile continuous wall using the steel sheet pile.

The steel sheet pile having joints at both outside ends includes an electrical insulating layer to obtain an electrical insulating state at a joint part to an adjacent steel sheet pile in a region that faces the joint part of the adjacent steel sheet pile, out of a fitting surface of the joint part when at least one joint part out of the joint parts is in a fitted state to the joint part of the adjacent steel sheet pile. If necessary, the steel sheet pile is formed such that a part or the whole surface of the steel sheet pile surface excluding the joint parts is covered with the electrical insulating layer. The steel sheet pile continuous wall is formed by pressing the steel sheet piles into soil.
