Provided are a polyvinyl alcohol aqueous solution capable of suppressing contamination by components other than polyvinyl alcohol, minimizing bubbles, and forming a film having exceptional adhesiveness with a base material, and a laminated film using this polyvinyl alcohol aqueous solution. The present invention is a polyvinyl alcohol aqueous solution containing polyvinyl alcohol, a surface tension regulator, and water, wherein the surface tension regulator is at least one selected from a group comprising polyether silicone compounds, glycerin compounds, cyclic hydrocarbon compounds, propylene glycol compounds, and fatty acid ester compounds, the polyvinyl alcohol aqueous solution contains 500-10,000 parts by weight of water per 100 parts by weight of polyvinyl alcohol, and the surface tension is 45-72 mN/m. |
