PROBLEM TO BE SOLVED: To improve the working efficiency by providing an anticorrosive sheet formed of an anticorrosive sheet-like base part and a projection part having a locking part at the tip of a leg part protruded from one side of the base, and a reinforcing layer for imparting form rigidity. SOLUTION: An anticorrosive sheet 3 having a sheet-like base part 5 having a sheet thickness T2 of about 1.0-5.0 mm and a plurality of anchor-like projection parts 2 protruded from one side S of the base part 5 is formed of high density polyethylene. The projection part 2 is formed of a leg part 6 protruded from the base part 5 and an engagingly locking part 7 swollen at the tip of the leg part 6, and a number of projection parts 2 are dotted in square or zigzag form. A reinforcing layer 4 consisting of resin mortar or the like is applied to the one side S of the base part 5 in an uniform thickness so as to protrude the leg part 6 of the projection part 2 from the reinforcing layer 4. Accordingly, the bonding strength with concrete can be significantly improved.
