Abstract: This invention provides an adhesive agent with a stronger adhesive force that can adhere and be peeled reversibly with the irradiation of light. With the use of a liquid crystalline polymer compound containing azobenzene or a sugar alcohol derivative containing a hydroxyl group and azobenzene, a photo-reactive adhesive agent that can strongly adhere to and be peeled from a substrate reversibly with the irradiation of light can be obtained.
