Abstract
The present invention relates to a laminate including a two-dimensional material and an adhesive sheet having a base material and an adhesive layer whose adhesive force decreases due to ultraviolet rays or heat, in which an adhesive force A at 25° C. of the adhesive layer before the ultraviolet rays or heat applies, to a silicon wafer is 1.0 N/20 mm to 20.0 N/20 mm when the adhesive layer is subjected to 180° peeling at a tensile speed of 300 mm/min, and a surface roughness of an adhesive surface of the adhesive layer after the ultraviolet rays or heat has been applied is 0.01 μm to 8.00 μm.
