Claim Text:
1. A method for manufacturing a transparent gas barrier film for an organic electroluminescence element comprising a substrate having thereon a gas barrier layer, wherein: the method comprises a step of forming the gas barrier layer on the substrate by a plasma CVD method using an organic silicon compound as a raw material gas and an oxygen gas as a decomposition gas, the gas barrier layer forming step is carried out under a condition so that a carbon content of the gas barrier layer in the thickness direction repeatedly changes more than two times from high value, via intermediate value, low value and intermediate value, to high value, the carbon content is defined by the formula: number of carbon atoms/total number of atoms×100, and a density of the gas barrier layer changes in the range of 1.90 g/cm
