Abstract:
A pressure-sensitive adhesive layer is obtained by applying and drying an aqueous dispersion type pressure-sensitive adhesive composition. On a surface of the pressure-sensitive adhesive layer, the number of a concave portion having a depth in a thickness direction of 0.2 to 20 μm and a maximum length along the surface of 1 to 10 mm is 5 or less per 1 m2.
