    摘要: A water-barrier laminate having a water-trapping layer (1) in which a hygroscopic agent is dispersed, wherein a hygroscopic agent has such a hygroscopic property that the ratio (Ax/Ay) of a hygroscopic amount Ax at a relative humidity of 80% and a hygroscopic amount Ay at a relative humidity of 30% is not less than 3, and the water-trapping layer is positioned between the two inorganic barrier layers (3a) and (3b). The water-barrier laminate exhibits barrier property against the water over extended periods of time.
