PROBLEM TO BE SOLVED: To provide an intermediate film for laminated glass which can obtain laminated glass excellent in heat shielding properties, and can keep excellent heat shielding properties of the laminated glass over a long period of time, and to provide a laminated glass using the intermediate film for laminated glass.SOLUTION: An intermediate film 1 for laminated glass includes a heat shielding layer 2 and an ultraviolet shielding layer 3. The heat shielding layer 2 contains: a thermoplastic resin; heat shielding particles; and at least one component selected from a phthalocyanine compound, a naphthalocyanine compound and an anthracyanine compound. The heat shielding layer 2 contains 0.2 wt.% of the above described components based on 100 wt.% of the heat shielding layer 2. The ultraviolet shielding layer 3 contains a thermoplastic resin and an ultraviolet shielding agent. A laminated glass has first and second laminated glass constituent members, and an intermediate film sandwiched between the first and second laminated glass constituent members. The intermediate film is the intermediate film 1 for laminated glass.SELECTED DRAWING: Figure 1 【課題】遮熱性に優れた合わせガラスを得ることができ、かつ該合わせガラスの優れた遮熱性を長期間にわたり維持できる合わせガラス用中間膜、及び該合わせガラス用中間膜を用いた合わせガラスを提供する。【解決手段】本発明に係る合わせガラス用中間膜１は、遮熱層２と、紫外線遮蔽層３とを備える。遮熱層２は、熱可塑性樹脂と、遮熱粒子と、フタロシアニン化合物、ナフタロシアニン化合物及びアントラシアニン化合物の内の少なくとも一種の成分とを含み、遮熱層２は、遮熱層２の１００重量％中、上記成分を０．２重量％以下で含有する。紫外線遮蔽層３は、熱可塑性樹脂と、紫外線遮蔽剤とを含む。本発明に係る合わせガラスは、第１，第２の合わせガラス構成部材と、該第１，第２の合わせガラス構成部材の間に挟み込まれた中間膜とを備える。該中間膜が、本発明に係る合わせガラス用中間膜１である。【選択図】図１
