Abstract: A gas barrier packaging material precursor, includes a support; an adhesion layer on one surface of the support; and a barrier layer and a protective layer formed adjacent each other on the adhesion layer. The adhesion layer contains a silicon compound composite. The protective layer is formed of a coating liquid containing a polyvalent metal compound, a polyester resin, and a dispersant, with the polyvalent metal compound being about 40 to about 90 mass % relative to 100 mass % . When the barrier layer is separated from the gas barrier packaging material precursor to measure an infrared absorption spectrum of the barrier layer by a transmission method, a ratio (α/β) of a maximum peak height (α) of absorbance in a range of about 1490 to about 1659 cm−1 to a maximum peak height (β) of absorbance in a range of about 1660 to about 1750 cm−1 is less than about 1.
