PROBLEM TO BE SOLVED: To provide a nail correction jig that can correct deformed nail by a simple method in a short term, and without causing the onset of refractory allergy, safely with less pain.SOLUTION: A nail correction jig 1 includes: a wire rod part 2 integrally formed by polymeric materials, having the elasticity and with a needle tip 2a molded at the one end； and a flat-shaped locking part 3 molded in the other end of this wire rod part. The needle tip of the wire rod part is inserted from the backside of the nail in the surface side direction to a first hole formed at one end in the width direction of the nail, and is moved until the surface of the locking part is made to comply with a nail bed and the locking part is locked in the backside of the nail. Also, the needle tip of the wire rod part is inserted from the surface side of the nail in the backside direction with respect to a second hole formed at the other end in the width direction of the nail, and the middle part of the wire rod part is moved until conforming to the surface of the nail. Also, the wire rod part exposed in the backside of the nail is bent along the backside of the nail, and then a surplus portion is cut. The shape, the dimension and the elasticity are optimized in order to be worn.SELECTED DRAWING: Figure 2【課題】簡単な方法で短期間に、かつ難治性アレルギーの発症を誘発せず安全に疼痛を少なく変形爪を矯正することができる爪矯正用治具を提供する。【解決手段】爪矯正用治具１は、ポリマー材料により一体成形され、弾性を有しその一端に針状先端２ａが成形されてなる線材部２と、この線材部の他端に成形された扁平形状の係止部３とを備え、爪甲の幅方向一端に形成された第１の孔に対し、上記線材部の前記針状先端を前記爪甲の裏側から表側方向に挿通させ、上記係止部がその表面を爪床に沿わせて爪甲の裏側に係止するまで移動させると共に、爪甲の幅方向他端に形成された第２の孔に対し、上記線材部の前記針状先端を前記爪甲の表側から裏側方向に挿通させ、線材部の中途部が爪甲の表面に沿うまで移動させると共に、爪甲の裏側に露出した線材部を爪甲の裏側に沿わせて折曲したのち余剰部分を切断する。装着されるべく形状、寸法、弾性が最適化されている。【選択図】図２
