Abstract:
The invention provides a gas barrier laminated film having high impact resistance when a heterolayer is formed on a thin film layer. The laminated film includes a flexible substrate and a thin film layer formed on at least one surface of the substrate, wherein the thin film layer contains Si, O, and C, and the ratio of the number of carbon atoms to the number of silicon atoms which is calculated using peaks each corresponding to each binding energy of 2p of Si, 1s of O, 1s of N, and 1s of C obtained from wide scan spectrums is in the range defined by the following formula (1) when the surface of the thin film layer is subjected to X-ray photoelectron spectrometry, and a intensity ratio of a peak intensity (I2) at 1240 to 1290 cm−1 to a peak intensity (I1) at 950 to 1050 cm−1 is in the range defined by the following formula (2) when the surface of the thin film layer is measured by an ATR method in infrared spectrometry: 0.01<C/Si≤0.02  (1)0.01≤I2/I1<0.05  (2).
