Abstract
A laminated film exhibits a certain adhesive property to various adherends having shapes or different irregularity shapes. The laminated film includes a resin layer A on one surface of a substrate and a resin layer B on the other surface. The resin layer A has a ten-point average surface roughness Rz(a) of 1.5 μm or more and 5.0 μm or less and a storage elastic modulus G' at 25° C. and 1 Hz of 3.0×10Pa or more.
