An object of the present invention is to provide a laminated film which can prevent transmission of the water vapor at the high level, and has good flex resistance, and the present invention provides a laminated film comprising at least a gas barrier layer and an inorganic polymer layer being laminated on a resin substrate, wherein concerning a distance from a surface of the inorganic polymer layer in a film thickness direction of the layer and the ratio of an oxygen atom to a total amount of a silicon atom, an oxygen atom, a carbon atom and a nitrogen atom (oxygen atomic ratio), the ratio of a value of the oxygen atomic ratio O/(total amount of Si, O, C and N) in a region from a surface on a side opposite to the gas barrier layer up to 30% of a film thickness of the inorganic polymer in a depth direction to a value of the oxygen atomic ratio O/(total amount of Si, O, C and N) in a region from 30% of a film thickness of the inorganic polymer layer in a depth direction up to a surface on a side of the gas barrier layer is 1.05 or more.
A laminated film comprising at least a gas barrier layer and an inorganic polymer layer being laminated on a resin substrate,
A process for manufacturing a laminated film comprising at least a gas barrier layer and an inorganic polymer layer being laminated on a resin substrate, comprising:
