PROBLEM TO BE SOLVED: To provide a film which is enough improved in gas-barrier properties under high humidity without being subjected to a complicated process and excellent in strength of a coating layer, transparency, and smoothness. SOLUTION: In the gas-barrier laminated film, a treatment layer in which anchor coat treatment is applied to at least one side of a polymer film is coated with a coating layer 0.05-3.0μm thick of a coating composition containing a water soluble polymer, a swellable synthetic mica mineral having an average particle size of 0.05-10μm and diffraction peak relative intensity obtained by powder X-ray diffraction analysis expressed by [I<SB>d=9.6Å</SB>]/[I<SB>d=12.4Å</SB>]×100≤2 and [I<SB>d=4.0Å</SB>]/[I<SB>d=12.4Å</SB>]×100≤10, and a film strength improving agent.
