PROBLEM TO BE SOLVED: To provide a hat-shaped steel sheet pile structure having an anticorrosive structure and a steel sheet pile used for its structure, superior in workability when installing a cover plate, by surely installing the cover plate, even if a joint part is dislocated, when preventing corrosion of the joint part by the cover plate, when constructing a hat-shaped steel sheet pile. SOLUTION: A baseplate is fixed along a claw part on a double anticorrosive coating in the vicinity of the claw part of the respective connected steel sheet piles by being electrically insulated from the steel sheet piles. The joint part is covered with the cover plate by welding the cover plate composed of a corrosion resistant metallic plate for covering the joint part, to the baseplate by spot welding, in a state of interposing an anticorrosive sheet between a pair of baseplates arranged by sandwiching the joint part.
