Peel-off detection label

A peel detection label that is a laminate comprising a support, a pattern layer formed in a part of a surface of the support, and a pressure-sensitive adhesive laminate comprising a low modulus layer (X), a high modulus layer (Y) and a pressure-sensitive adhesive layer (Z) in that order,

• wherein the low modulus layer (X) comprises an n-layered structure (where n is an integer of 1 to 10) having a first surface in contact with the support and the pattern layer, and a second surface in contact with the high modulus layer (Y),
• a thickness-average shear storage elastic modulus of the low modulus layer (X), as represented by the following expression (1), is 8.0×104 Pa or more and 6.0×105 Pa or less:

• where G′(Xk) represents a shear storage elastic modulus G′ at 23° C. of the k′th layer (Xk) from the support side in the low modulus layer (X);
• T(Xk) represents a thickness ratio of the layer (Xk)=thickness of layer (Xk)/total thickness of low modulus layer (X);
• and n represents an integer of 1 to 10, and
• when the pressure-sensitive adhesive layer (Z) of the peel detection label is attached onto an adherend and then peeled from the adherend, interfacial peeling occurs between the support and the pattern layer, whereby the presence or absence of peeling of the peel detection label from the adherend becomes visually detectable.
