An attachment for attaching an artificial fingernail to a natural fingernail. The attachment includes a double-sided adhesive strip. The double-sided adhesive strip is made of an elastic material which reduces an elastic material width when a pull is exerted in a longitudinal direction so as to reduce an adhesive force, and a grip tab which projects at a front end of the double-sided adhesive strip. The grip tab is arranged underneath an outwardly projecting portion of the artificial fingernail once the artificial fingernail has been attached. The pull on the double-sided adhesive strip is exerted via the grip tab.

The present invention provides a polymer compound peeling agent usable for peeling as many types of polymer compounds as possible and capable of reducing a burden required for a peeling treatment when a polymer compound having adhered to an adhesion object is peeled. The polymer compound peeling agent for peeling a polymer compound having adhered to an adhesion object contains a photoresponsive liquid crystal material having a phase structure reversibly transitioning between an isotropic phase and a liquid crystal phase due to photoisomerization based on irradiation lights of different wavelengths. When the polymer compound is adhered to the adhesion object, the photoresponsive liquid crystal material is contained in the polymer compound with the phase structure set to the isotropic phase, and the phase structure of the photoresponsive liquid crystal material is allowed to transition from the isotropic phase to the liquid crystal phase by photoisomerization based on the light irradiation.
