Abstract
A laminated film includes a base film and a coating layer which contains organic particles and is provided on a surface of the base film, wherein a ratio (SRz/d) of a surface roughness (SRz) and a coating thickness (d) on a surface of the coating layer is 12.5 or more, and the organic particle is made of a thermoplastic resin including an ether bond while the coating layer is made of a binder resin including at least one selected from a sulfonic acid group, a carboxylic acid group, a hydroxyl group and a salt of them.
