Abstract: A method of producing a gas barrier laminate of the present disclosure includes a step of forming a coating film on a surface of a base film or a laminate including the base film, the coating film containing zinc ions, at least one of metal alkoxide and a hydrolysate thereof, and an aqueous polymer, and a step of drying the coating film to form a gas barrier layer on the surface of the base film or the laminate including the base film. A gas barrier laminate of the present disclosure includes a base film or a laminate including the base film, and a gas barrier layer provided on a surface of the base film or the laminate including the base film. In the gas barrier laminate, the gas barrier layer contains zinc dispersed in the gas barrier layer and an organic-inorganic composite.
