To facilitate the handling of artificial nails by enabling the artificial nails to be carried while preventing them from being scattered, and also, from becoming bulky.

For this artificial nail device, a plate-like base material 2 is equipped with a plurality of the artificial nails N1 to N5. A slit and a connecting section which connects the plate-like base material 2 with the artificial nail are provided around each artificial nail. For example, the slit S11 and the slit S12, the connecting C11 and the connecting section C12 are provided around the artificial nail N1. The plate-like base material 2 is formed into, e.g., a card shape. A user of the artificial nail cuts the connecting section C11 and the connecting section C12 when the artificial nail is used, and uses the artificial nail by separating it from the plate-like base material 2.
