摘要： Provided is a polyvinyl acetal film which, when used as an intermediate film for a laminated glass, can provide a laminated glass that exhibits a low degree of yellowness and excellent surface appearance, and which is thus useful as a sealing material or intermediate film that can prolong the life of a laminated glass provided with a solar cell or a functional unit. Further, the content of corrosion-causing substance in the polyvinyl acetal film is low, so that the polyvinyl acetal film permits high-temperature lamination and thus ensures excellent productivity. Also provided are a solar cell module and a laminated glass prepared using the polyvinyl acetal film. A plasticized polyvinyl acetal film which comprises 15 to 60 parts by mass of a plasticizer having a total number of 28 or more of carbon atoms and oxygen atoms constituting a molecule based on 100 parts by mass of a polyvinyl acetal resin, and which has an acid value of 5.0 meq/kg or less.
