Abstract:
A laminated material having a barrier film containing a barrier layer on at least one surface of a substrate film that is a silicon oxide film having an atomic ratio in a range of Si:O:C=100:140 to 167:20 to 40, peak position of infrared-ray absorption due to Si—O—Si stretching vibration between 1060 to 1090 cm−1, a film density in a range of 2.6 to 2.8 g/cm3, and a distance between grains of 30 nm or shorter.
