PROBLEM TO BE SOLVED: To provide a thin-bladed grindstone securing quality of a product even if warp or deformation and distortion occur, and also to provide a method for correcting a warp of the same. SOLUTION: In a thin-bladed grindstone, a circular hole 2 concentric with the grindstone is provided in a circular thin platy grindstone body 1, a peripheral edge of the circular hole 2 is defined as an inner peripheral edge 3 of the grindstone body 1, and at least an outer peripheral edge 4 of the grindstone body 1 is defined as an abrasive grain layer 5. The grindstone body 1 is formed in a C-shaped form by providing an opening 6, which reaches from the inner peripheral edge 3 to the outer peripheral edge 4, in the grindstone body 1.
