PROBLEM TO BE SOLVED: To provide a corrosion protection method to a steel in a concrete structure by which the steel keeps long-term corrosion protection function after constructed and has excellent durability, and to provide a continuous fiber sheet used for the method. SOLUTION: The continuous fiber sheet 1, e.g., used for the electric corrosion protection of a reinforced concrete structure is provided. In the continuous fiber sheet 1, an electroconductive metal wire 13 is knitted into a synthetic resin fiber or an inorganic fiber sheet, and the sheet is provided with a plurality of holes 14 passing through the surface and back thereof. The continuous fiber sheet is fixed to the surface of a reinforced concrete structure with an adhesive having electroconductivity, and electric corrosion protection is performed in such a state that the surface of the continuous fiber sheet is covered with a holding material holding an alkaline electrolytic aqueous solution.
