Abstract: A gas barrier laminate with a total thickness of 100 μm or less, including a plastic base material (I) and a gas barrier layer (II) laminated on said plastic base material, wherein (1) plastic base material (I) includes a metal-containing layer including at least one metal and a metal compound and a resin component, (2) the total content of metal and metal compound in said metal-containing layer is 0.1 to 70% by mass, (3) gas barrier layer (II) contains polycarboxylic acid, (4) metal-containing layer and gas barrier layer are laminated so that they are in direct contact with each other, and (5) gas barrier laminate is treated at a temperature of 95° C. for 30 minutes. (5) the gas barrier laminate has an oxygen transmission rate of 300 ml/(m2·day·MPa) or less under a temperature of 40° C. and a humidity of 90% RH after hot water treatment for 30 minutes at 95° C.
