PROBLEM TO BE SOLVED: To provide a cross-section restoring structure of a reinforced concrete structure capable of easily installing a sacrifice anode material, and capable of further preventing corrosion of a reinforcement without causing complicated maintenance work over a long period after restoring a cross section of the reinforce concrete structure. SOLUTION: A linear sacrifice anode material 3 is attached to a front part of its deep layer part reinforcement 62b in the axial direction of the deep layer part reinforcement 62b of exposing the front part from a bottom surface 2a of a concrete removing part 2, that is, to the deep layer part reinforcement 62b so as to contact with a surface of an exposure part of the deep layer part reinforcement 62b. A curved form part 3a of the linear sacrifice anode material 3 is sandwiched between an elastic spring fixture 4 and a surface layer part reinforcement 62a, and is fixed in a state of directly contacting with an outer peripheral surface of the surface layer part reinforcement 62a so that an electric current can be carried. A cross-section restoring member 5 is mainly composed of cement-based mortar, and rust preventives having a property of permeating and diffusing inside the reinforced concrete structure 60, is mixed with its mortar as an additive.
