Abstract: 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.
