NOVELTY - A laminated film is formed by laminating coating layer, inorganic thin film layer and gas-barrier resin composition layer on at least single surface of base film, in order optionally using other layer. The coating layer is formed from resin composition containing resin which has oxazoline group, and acrylic resin. The peak intensity and film thickness of coating layer is calculated using a specific relationship. The gas-barrier resin composition layer is formed from the gas-barrier resin composition containing gas-barrier resin, inorganic laminar compound and additive.    USE - Laminated film is used for solar cell, electronic paper, organic electroluminescent element, semiconductor element, and packaging material for foodstuff, pharmaceutical and industrial commodity.    ADVANTAGE - The laminated film has excellent adhesiveness, stability, homogeneous characteristics and gas-barrier property with respect to oxygen and water vapor, and is economically manufactured. The delamination of the laminated film is suppressed even after retort process.    DETAILED DESCRIPTION - A laminated film is formed by laminating coating layer, inorganic thin film layer and gas-barrier resin composition layer on at least single surface of a base film, in order optionally using other layer. The coating layer is formed from resin composition containing resin which has an oxazoline group, and acrylic resin. The peak intensity and film thickness of coating layer is calculated using a relation: 0.03 less than or equal to (P1 divide by P2) divide by D(nm) less than or equal to 0.15 (I), where P1 is peak intensity of peak having an absorption maximum peak in the region of 1655 plus minus 10 cm-1, P2 is peak intensity of peak having an absorption maximum peak in the region of 1580 plus minus 10 cm-1 and D is film thickness of 5-150 nm. The gas-barrier resin composition layer is formed from the gas-barrier resin composition containing gas-barrier resin which contains an ethylene-vinyl alcohol-type copolymer, inorganic laminar compound and additive chosen from coupling agent and crosslinking agent. The content of inorganic laminar compound is 0.1-9 %mass with respect to 100 %mass of total content of gas-barrier resin composition.
