PURPOSE: To attain reflection of a heat ray by vapor depositing an ITO film in a glass surface.

CONSTITUTION: An ITO film 2 is evaporated in one side of a surface of a glass 1, and a heat ray reflecting film 6, alternately evaporating a plurality of layers of metal thin films 4, 5 of different index of refraction, is formed on this ITO film, to control a film thickness, so as to cut a 780 to 1500nm heat ray. Further, in one side of the surface of the glass 1, a plurality of layers of the metal thin films 4, 5 of different index of refraction and an alternately evaporated color temperature converting visible light reflecting film 7 are formed, and by controlling film thickness, a 780 to 250Onm heat ray is cut, also to reflect a 200 to 380nm ultraviolet ray.
