Gas barrier film laminate, adhesive film, and electronic component

Abstract

The present invention relates to a gas barrier film laminate comprising at least two gas barrier films, the gas barrier film laminate having a configuration in which two adjacent gas barrier films are stacked through a pressure-sensitive adhesive layer, and the pressure-sensitive adhesive layer having a shear load reduction ratio α (%) given by an expression (I) in claim 1, of 70% or less; and an adhesive film that is used to produce a gas barrier film laminate that includes at least two gas barrier films, and has a configuration in which two adjacent gas barrier films are stacked through a pressure-sensitive adhesive layer, the adhesive film comprising at least a gas barrier film and a pressure-sensitive adhesive layer that are stacked adjacent to each other, the pressure-sensitive adhesive layer having a shear load reduction ratio α (%) given by an expression (I) in claim 11, of 70% or less. Provided is a gas barrier film laminate that exhibits an excellent water vapor barrier capability, and rarely shows a deterioration in external appearance (e.g., air bubbles) even when subjected to a high temperature and a high humidity for a long time, the adhesive film that is useful for producing the gas barrier film laminate, and an electronic member that includes the gas barrier film laminate.
