    Abstract: Provided by an embodiment of the present invention is a coating liquid for producing a gas barrier laminate, the coating liquid containing a carboxyl group-containing polymer (a), polyvalent metal-containing particles (b), a surfactant (c), a specific silicon-containing compound (d), and an organic solvent (e). In the coating liquid: the equivalence ratio (b t /a t ) of the product (bt) of the number of moles and the valency of the polyvalent metal contained in the polyvalent metal-containing particles (b) relative to the number of moles (at) of carboxyl groups contained in the carboxyl group-containing polymer (a) is 0.45 or more and 0.9 or less; and the molar ratio (d t /a t ) of the number of moles (dt) of the silicon-containing compound (d) relative to the number of moles (at) of the carboxyl groups is 0.7% or more and 7.5% or less.
