[Solution] A nail correction tool for correcting deformed nails, the nail correction tool being integrally formed by means of a polymer material, and being provided with an elastic wire rod part on which a needle-like tip is formed on one end, and a flat latching part which is formed on the other end of the wire rod part, wherein: the needle-like tip of the wire rod part is inserted into a first hole, which is formed on one end in the width direction of a nail plate, in the direction from the rear side to the front side of the nail plate, and the surface of the latching part is moved along a nail bed until the latching part latches onto the rear side of the nail plate; the needle-like tip of the wire rod part is inserted into a second hole, which is formed on the other end in the width direction of the nail plate, in the direction from the front side to the rear side of the nail plate and is moved until the middle part of the wire rod part reaches the surface of the nail plate; and the wire rod part that exposes from the rear side of the nail plate is bent along the rear side of the nail plate and the excessive portion of the wire rod part is cut. The shape, size, and elasticity of the present invention is optimized so that same can be attached as mentioned above.La présente invention concerne un outil de correction de clous pour la correction de clous déformés, l'outil de correction de clous étant formé d'un seul tenant en un matériau polymère, et étant pourvu d'une partie tige de fil élastique sur laquelle une pointe de type aiguille est formée sur une extrémité, et d'une partie d'encliquetage plate qui est formée sur l'autre extrémité de la partie tige de fil, dans lequel : la pointe de type aiguille de la partie tige de fil est insérée dans un premier trou, qui est formé sur une extrémité dans le sens de la largeur d'une plaque à clou, dans la direction du côté arrière au côté avant de la plaque à clou, et la surface de la partie d'encliquetage est déplacée le l
