    摘要: To provide a fluorophosphates glass having a weather-resistant property and having an O2−/P5+ ratio even after production, which is set so that Cu2+ can be added with a quantity of such a degree suppressing an absorption of a visible light while absorbing a near-infrared light, and a method for producing the same, and a near-infrared light absorbing filter, wherein a molar ratio of a content of O2− with respect to a content of P5+ (O2−/P5+) in the fluorophosphates glass, is 3.2 or more and less than 3.4, and a molar ratio of a content of F− with respect to a total content of O2− and F− (F−/(O2−+F−)) in the fluorophosphates glass is 0.05 or more and 0.25 or less.
