PROBLEM TO BE SOLVED: To provide an intermediate film for laminated glass, which can provide the laminated glass capable of suppressing generation and growth of foaming; and to provide a multilayer intermediate film for the laminated glass, using the intermediate film.SOLUTION: Intermediate films 2, 21 for the laminated glass contain a polyvinyl acetal resin and a plasticizer. The maximum value of tan δ at 200°C on condition that the angular frequency ω is 10≤ω≤10of the intermediate films 2, 21 is ≤1.00. The multilayer intermediate film 1 for the laminated glass includes a first intermediate film 2 for the laminated glass, and a second intermediate film 3 for the laminated glass laminated on a first surface 2a of the first intermediate film 2 for the laminated glass, and containing the polyvinyl acetal resin and the plasticizer. |
