The gas barrier laminate of the present invention includes a base material and a gas barrier layer laminated on the base material. The gas barrier layer comprises a hydrolysis condensate of at least one compound (L) containing a hydrolyzable characteristic group, and a polymer containing at least one functional group selected from a carboxyl group and a carboxylic anhydride group It consists of a composition containing (X). At least a part of the —COO— group of the polymer (X) is neutralized and / or reacted with the compound (P) containing two or more amino groups. At least a part of the —COO— group of the polymer (X) is neutralized with a divalent or higher valent metal ion. The ratio of [equivalent of amino group contained in compound (P)] / [equivalent of -COO-group of polymer (X)] is in the range of 0.2 / 100 to 20.0 / 100. |
