摘要： Provided is a method for peeling a PSA sheet adhered on a polarizing plate. The PSA sheet has a PSA layer. The PSA layer includes a layer A forming at least one surface of the PSA layer. Of the polarizing plate, the surface to which the PSA sheet is adhered is corona-treated or plasma-treated. The peeling method includes a water-peel step in which the PSA sheet is peeled from the polarizing plate, in a state where an aqueous liquid exits at the interface between the polarizing plate and the PSA sheet at the front line of peeling the PSA sheet from the polarizing plate, with the aqueous liquid allowed to further enter the interface following the movement of the peel front line.
