The purpose of the present invention is to provide a gas barrier laminate and a gas barrier laminate film which realize high gas barrier capability without conducting a high-temperature and high-humidity treatment, and have high gas barrier capability under high humidity conditions. This gas barrier laminate is provided with a gas barrier layer on at least one surface of a substrate or on the surface of the anchor coating layer of a substrate having an anchor coating layer. The gas barrier layer comprises a main coating layer (A) containing polycarboxylic acid polymer, a resin coating layer (B), and a polyvalent metal ion-supplying layer (C) containing a polyvalent metal compound, dispersant, and binder resin. The main coating layer (A) and polyvalent metal ion-supplying layer (C) are laminated with the resin coating layer (B) therebetween. The oxygen gas permeation degree as measured under the conditions of a temperature of 20ºC and a relative humidity of 80% is 10 cm3 (STP)/(m2·day·MPa) or less. |
