Abstract: The invention relates to a peel detection label that is a laminate including a support, a pattern layer formed in a part of the surface of the support, and a pressure-sensitive adhesive laminate having at least a low modulus layer (X), a high modulus layer (Y) and a pressure-sensitive adhesive layer (Z) in that order, in which the low modulus layer (X has a surface in contact with the support and the pattern layer and a surface in contact with the high modulus layer (Y), and satisfies the following requirement (1): Requirement (1): when the pressure-sensitive adhesive layer (Z) of the peel detection label is attached to an adherend and then the peel detection label is peeled off from the adherend, the maximum vertical tensile stress applied to an element of the low modulus layer (X) that is located closest to the support is 0.19 MPa or more when analyzed by a finite element method using Abaqus.
