Abstract: This gas barrier laminate comprises a base layer; a gas barrier layer laminated on one surface (A) of the base layer, directly or with another layer sandwiched therebetween; a protective film (α) laminated directly on the gas barrier layer; and a protective film (β) laminated on a surface (B) opposite to the surface (A) of the base layer, directly or with another layer sandwiched therebetween, wherein the gas barrier layer contains a specific inorganic compound, and an adhesion at the time of peeling the protective film (α) and an adhesion at the time of peeling the protective film (β) under specific conditions are both less than or equal to specific values. By means of this invention, there is provided a gas barrier laminate having a base layer, a gas barrier layer, and protective films, in which each of the protective films can be peeled off without adversely affecting the external appearance of an exposed surface, and even after the protective film is peeled off, the original water vapor-blocking properties are maintained in the remaining laminate.

Abstract: The present invention provides a laminate film comprising at least a base and a gas barrier layer, elongation strain (ε) generated in a surface of the gas barrier layer, which is calculated by a following formula (1), is 0.8% or less; an electronic device member including the laminate film; and an electronic device equipped with the electronic device member. In formula (1), T is a distance [m] from a surface farthest from the gas barrier layer to the gas barrier layer in a thickness direction of the laminate film, and λ is a distance, from the surface of the laminate film, of a hypothetical plane (α) in the laminate film in which stress does not occur. According to the present invention, there are provided a laminate film excellent in gas barrier properties and bending properties, an electronic device member including this laminate film, and an electronic device equipped with this electronic device member. ε=(T−×)/{(3×10−3)+λ}×100  (1)
