To provide an artificial nail fixing material and an artificial nail fixing tape capable of fixing the artificial nail at a high fixing force and having an easily peeling property.

When a temperature sensitive adhesive showing fluidity at a temperature higher than the surface temperature of an own nail and crystallized at the temperature higher than the surface temperature of the own nail is used as the artificial nail fixing material, the artificial nail can be fixed to the own nail at the high fixing force, and when the artificial nail is peeled from the own nail, the artificial nail can be easily peeled. Practically, this fixing material is used as an artificial nail fixing tape 4 formed by providing temperature sensitive adhesive layers 2 and 21 which show fluidity at a temperature higher than the surface temperature of the own nail and are crystallized at the temperature higher than the surface temperature of the own nail, on both surfaces of a base material film 3.
