Gas barrier film and method of producing gas barrier film

A method of producing a gas barrier film comprising:

• alternately forming an organic layer and an inorganic layer on one surface of a support such that two or more layers of the organic layers and two or more layers of the inorganic layers are formed,
• wherein in a case where the organic layer is formed on a surface of the support, an organic layer which is formed on the surface of the support is an underlying organic layer, and an organic layer which is formed between the inorganic layers is an intermediate organic layer, the underlying organic layer and the intermediate organic layer are formed such that a thickness of the intermediate organic layer is 0.05 to 0.5 μm, and a ratio between the thickness of the intermediate organic layer and a thickness of the underlying organic layer is 0.1 or less, and,
• the intermediate organic layer is formed by performing a coating step of applying a polymerizable composition containing (meth)acrylate represented by Formula (1) to the inorganic layer, a drying step of heating and drying the polymerizable composition applied to the inorganic layer, and a curing step of curing the dried polymerizable composition,
• in Formula (1), R1's each represent a substituent and may be the same or different from each other;
• and n's each represent an integer of 0 to 5 and may be the same or different from each other, where at least one R1 includes (meth)acryloyl group.
