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.
