PROBLEM TO BE SOLVED: To provide a Low-E glass plate protective sheet excellent in long-term reliability. A Low-E glass plate protective sheet is provided. This protective sheet 10 includes an adhesive layer 2. The pressure-sensitive adhesive layer has an amount of chloride ions measured by hot water extraction of 105 μg or less per 1 g of the pressure-sensitive adhesive. Preferably, the chloride ion amount measured by hot water extraction is less than 8.0 μg per 1 g of the protective sheet, and the pressure-sensitive adhesive layer is a pressure-sensitive adhesive layer formed from a water-dispersed pressure-sensitive adhesive composition.
