摘要

Disclosed is a in the near infrared range is an absorbent glass with a high transparency in the region of the visible light and with excellent absorption properties in the near infrared range as well as with an excellent climate-proofing, etc. it is for use as in the near infrared range, the absorbent member and is suitable, as in a in the near infrared range is an absorbent filter, and in a in the near infrared range absorbing element, onto which the above mentioned, in the near infrared range has been applied absorbent glass. In the near infrared range, the absorbent glass contains, as a cationic% 25 to 45% p⁵⁺, 1 to 10% al³⁺, 15 to 30% of li⁺, 0,1 to 10% mg²⁺, 0,1 to 20% ca²⁺, 0,1 to 20% sr²⁺, 0,1 to 20% ba²⁺ and 1 to 8% cu²⁺, and contains, as the anionic components, 25 to 50 anionic% f^- and o^2-.
