To provide a glass with heat ray reflection film, capable of suppressing significantly, reduction of a heat ray reflection function, even in a high humidity, and significantly suppressing peeling of a shield film.SOLUTION: There is provided a glass with heat ray reflection film, the glass comprising: a glass substrate having a first surface, and having at least three sides in top view; a heat ray reflection film which is provided on the first surface of the glass substrate; a shield film which is provided on a peripheral edge of the first surface, along at least one of the at least three sides on the first surface side of the glass substrate, and the shield film comprising outer end and inner end; and a water repellent film provided on the heat ray reflection film. In top view, the water repellent film is provided to cover the inner end of the shield film, in the glass.SELECTED DRAWING: Figure 2 【課題】多湿環境においても、熱線反射機能の低下を有意に抑制できる上、遮蔽膜の剥離を有意に抑制することが可能な、熱線反射膜付きガラスを提供する。【解決手段】熱線反射膜付きガラスであって、第１の表面を有し、上面視、少なくとも３つの辺を有するガラス基板と、前記ガラス基板の前記第１の表面に設置された熱線反射膜と、前記ガラス基板の前記第１の表面の側において、前記少なくとも３つの辺の少なくとも一つに沿って、前記第１の表面の周縁部に設置された遮蔽膜であって、外端部および内端部を有する、遮蔽膜と、前記熱線反射膜の上に配置された撥水膜と、を有し、上面視、前記撥水膜は、前記遮蔽膜の前記内端部を覆うように配置されている、熱線反射膜付きガラス。【選択図】図２
