Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a gas barrier laminate provided with a hygroscopic layer having transparency and high hygroscopicity. SOLUTION: The gas barrier laminate includes a gas barrier film layer (A) having a gas barrier layer and a hygroscopic layer (B) containing one or more kinds of polyalkylene oxide, acrylate nano-particles and an organometallic complex at least on one surface of a base material. Since polyalkylene oxide, acrylate nano-particle and organometallic complex have high saturated hygroscopicity even under low humidity, the gas barrier laminate exhibits high hygroscopicity even under such a low humidity atmosphere that the hygroscopic layer is held between the gas barrier films.
