Abstract: A laminate, including at least a resin film and a pressure sensitive adhesive layer provided on one surface of the resin film, in which the resin film in the laminated state has a surface roughness Sa equal to or lower than 30 nm that is measured in a visual field of 4 mm×5 mm within a surface opposite to the surface having the pressure sensitive adhesive layer, a thickness of the pressure sensitive adhesive layer is equal to or smaller than 100 μm, and a maximum value of a loss tangent of the pressure sensitive adhesive layer at a frequency of 1 Hz is found in a temperature range of 0° C. to −40° C. and is equal to or greater than 1.3.
