1. A protection method for a Low-E glass plate, the protection method comprising protecting the Low-E glass plate that includes a Low-E layer comprising a zinc component with a protective sheet that includes a substrate and a pressure-sensitive adhesive layer provided to at least one face of the substrate by applying the pressure-sensitive adhesive layer to the Low-E layer,
wherein the protection method further comprises:
preparing a pressure-sensitive adhesive composition by adding an adsorbent capable of adsorbing ammonia to a pressure-sensitive adhesive-containing solution;
applying the pressure-sensitive adhesive composition to the at least one face of the substrate to form a sheet with the pressure-sensitive adhesive layer on the substrate; and
using the sheet with the pressure-sensitive adhesive layer as the protective sheet.
