Abstract: Disclosed is a French artificial nail including an artificial nail body and a French part. The artificial nail body includes a cuticle edge facing the root of a fingernail and a free edge extending towards the tip of the fingernail and is curved downward toward both lateral sides thereof to form a curved surface. The French part is formed on the upper surface of the free edge of the artificial nail body. The artificial nail body is attached to a user's fingernail or toenail through glue and has a lower modulus than the French part. This flexibility of the artificial nail body prevents the formation of bubbles, the incidence of pain and the occurrence of pop-off resulting from glue shrinkage, contributing to an improvement in the wearability and reliability of the final product.
