PROBLEM TO BE SOLVED: To provide a method of preventing exfoliation of concrete pieces for positively preventing exfoliation of concrete pieces and eliminating the projection of an anchor bolt to suppress a degrading factor of concrete from the outside. SOLUTION: In this method of preventing exfoliation of concrete pieces, a cut-off agent 6 is injected from an injection hole 4 into a deep part of a crack 3 in a concrete structure 1, and after repairing the periphery of the crack 3 to form a smooth surface, a fiber sheet 9 is stuck to the smooth surface, and an adhesive is applied from the top. An anchor insertion hole 12 is bored in the concrete structure 1 from the surface of the fiber sheet 9 with the adhesive 10 applied, and after a part of the fiber anchor 15 is inserted into the anchor insertion hole 12 and bonded, the remaining part of the fiber anchor 15 is torn into small pieces and radially stuck to the upper face of the fiber sheet 9.
