To provide a resin film used for an intermediate film of laminated glass which can manufacture laminated glass excellent in breaking resistance, and can manufacture laminated glass which can suppress occurrence of air bubbles when the glass is stuck and is excellent in foaming resistance when a transparent plastic substrate in place of glass is used.SOLUTION: A resin film is used for an intermediate film of laminated glass which has a compression ratio when crept at 23°C and a load of 30 mN for 5 minutes of 10% or more and 40% or less, and a compression ratio when crept at 95°C and a load of 30 mN for 5 minutes of 45% or less.SELECTED DRAWING: Figure 1 【課題】防割性に優れる合わせガラスを作製できるとともに、ガラスを貼り合わせる際に気泡の発生を抑制することができ、且つガラスの代わりに透明プラスチック基板を用いた場合に耐発泡性に優れる合わせガラスを作製することが可能な、合わせガラスの中間膜に用いられる樹脂膜を提供すること。【解決手段】２３℃で、３０ｍＮの荷重で５分間クリープさせたときの圧縮率が、１０％以上４０％以下であり、且つ、９５℃で、３０ｍＮの荷重で５分間クリープさせたときの圧縮率が、４５％以下である、合わせガラスの中間膜に用いられる樹脂膜。【選択図】図１
