PROBLEM TO BE SOLVED: To provide a curled nail corrector capable of mounting a curled nail corrector on a curled nail more easily than the prior art.SOLUTION: A curled nail corrector 1 comprises an elastic member 10, and a pair of terminal members 20 having an insertion portion 22 and a hook portion 21. The hook portions 21 of the paired terminal members 20 are individually hooked on both side edge portions of a curled nail 40 so that the paired terminal members 20 are arranged on the two side edge portions of the curled nail 40. The elastic member 10 is arranged above the curled nail 40 such that it is inserted into the insertion portion 22 of the paired terminal members 20 and is warped. The curled nail corrector 1 corrects the curled nail 40 so that the two side edge portions of the curled nail 40 are pulled up through the paired terminal members 20 by the elastic force of the elastic member 10, thereby to correct the curled nail 40 in a manner to dissolute the curled nail 40.
