Abstract: Provided is a pressure sensitive adhesive sheet including a resin layer that is a multilayer structure containing at least a layer (Xβ), a layer (Y1), and a layer (Xα) laminated in this order, a surface (α) of the layer (Xα) of the resin layer having pressure sensitive adhesiveness, at least a constitutional component contained in the layer (Y1) being different from constitutional components contained in the layer (Xα) and the layer (Xβ), on the prescribed cross section (P1) of the pressure sensitive adhesive sheet, in a range of 250 μm in a horizontal direction freely-selected, a difference between a maximum value and a minimum value of the layer (Xα) being 3.00 μm or more, and a difference between a maximum value and a minimum value of the layer (Y1) being 5.00 μm or more.
