Provided is an adhesive sheet comprising a resin layer that is a multi-layer structure in which at least a layer (Xβ), a layer (Y1), and a layer (Xα) are layered in this order, wherein a surface (α) of the layer (Xα) has adhesive properties. At least a constituent component included in the layer (Y1) is different from constituent components included in the layer (Xα) and the layer (Xβ). In a predetermined cross section (P1) of the adhesive sheet, the difference between the maximum value and the minimum value of the thickness of the layer (Xα) within a discretionarily selected range that is 250 µm in the horizontal direction is 3.00 µm or greater, and the difference between the maximum value and the minimum value of the thickness of the layer (Y1) is 5.00 µm or greater. |
