Disclosed is a method for manufacturing artificial nails, each of which includes a cuticle end to be attached to the cuticle of a fingernail and a free edge disposed opposite the cuticle end. The method includes: a preparation step of supplying a film including a planar design surface and a bent support surface formed opposite the design surface; a design step of forming artificial nail patterns on areas of the design surface of the film defined by first end portions formed at the cuticle ends and second end portions formed at the free edges, the artificial nail patterns being formed such that the first end portions and the second end portions are formed at locations where the cuticle ends are smaller in thickness than the free edges; and a body molding step including a molding operation of forming the film into three-dimensional shapes in shaping molds including a plurality of artificial nail casts with fingernail shapes and reference plates connecting the artificial nail casts, and a cutting operation of cutting the film formed with a plurality of fingernail shapes into the individual fingernail shapes by a cutter located above the shaping molds. According to the method, the wearability of the artificial nails can be improved and the strength of the tips of the artificial nails can be maintained. In addition, various patterns can be applied to the artificial nails during the design printing.
