PROBLEM TO BE SOLVED: To provide an incurvated nail correction tool capable of optimizing a nail lifting force even though a hooking portion 30 and a connecting portion 20 have a simple structure integrally formed of synthetic resin. SOLUTION: A straightening tool main body 10 of an incurvated nail correction tool includes a pair of hooking portions 30 hooked on tip portions of nails, and a plate-like connecting portion 20 that connects the hooking portions 30 to each other and abuts on the surface of the nails. , Are provided. When both ends of the connecting portion 20 in the claw width direction are the end plate portions 22 and the other portions are the central plate portions 21, the hook portions 30 are provided on the end plate portions 22. The hooks 30 and the connecting portions 20 are integrally formed of synthetic resin. The plate thickness of the hook portion 30 is formed to be larger than the plate thickness of the central plate portion 21.
