<p>A heat-radiation reflective glass comprising a glass plate and a film formed on the glass plate. The film has composition comprising 65 to 96 % by weight of cobalt, 2 to 25 % by weight of chromium and 2 to 33 % by weight of iron based on the total metal weight per unit area, and has a layer thickness of 10 nm to 70 nm. In another embodiment, the film has composition comprising cobalt, chromium and iron in weight percentages within the ranges of 65 to 96 % by weight of cobalt, 2 to 25 % by weight of chromium and 2 to 33 % by weight of iron based on the total metal weight per unit area, in its part on the side coming into contact with the glass plate, and in weight percentages within the ranges that fulfill at least one of conditions i) 2 to 96 % by weight of cobalt, 2 to 8 % by weight or 18 to 96 % by weight of chromium and 2 to 96 % by weight of iron and ii) 2 to 96 % by weight of cobalt, 2 to 96 % by weight of chromium and 2 to 10 % by weight of iron based on the total metal weight per unit area, in its part on the outermost side, and has a layer thickness of 10 nm to 70 nm.</p> |
