Abstract

The invention relates to a gas barrier film laminate comprising at least two gas barrier films and a pressure-sensitive adhesive layer, the at least two gas barrier films being stacked through the pressure-sensitive adhesive layer, at least one of the at least two gas barrier films including a base formed of a plastic film, and at least one gas barrier layer provided on the base, and the pressure-sensitive adhesive layer being a layer formed using a rubber-based pressure-sensitive adhesive composition that includes a rubber-based compound. The invention also relates to an electronic member comprising the gas barrier film laminate. The gas barrier film laminate exhibits a high water vapor barrier capability, and does not show interfacial lifting at the end thereof.
