There is provided a gas barrier sheet that has high productivity, good gas barrier properties, and anticurling properties. In particular, a gas barrier sheet is provided that, even after a heat cycle test which is performed as a durability test for organic EL displays and the like, can suppress the occurrence of curling and can maintain gas barrier properties. The gas barrier sheet comprises a gas barrier film 3 provided on a base material 2. The gas barrier film 3 is an SiNxOy film, wherein x=0.5 to 1.5 and y=0.25 to 1, has an absorption intensity of IR absorption (830 cm−1 to 840 cm−1), corresponding to an Si—N bond, per unit thickness of 0.5×10−3/nm to 1.8×10−3/nm and has a refractive index of 1.7 to 2.1. |
