The present invention is a near infrared filter relates to a glass composition and a method for manufacturing a glass for a near infrared filter using the same, the glass composition for near infrared filter according to the present invention, lithium oxide (Li
2 O), sodium oxide (Na
2 O) or oxidation potassium (K
2 O) of at least two alkali 10 mol% of metal oxide to contain 40 mol%, the sodium oxide / (the lithium oxide + the sodium oxide) or the potassium oxide / (the sodium oxide + the potassium oxide the molar ratio of the) is characterized in that 0.25 to 0.75.
According to the present invention, prior to improve the moisture absorption problems of weak phosphoric acid-based parent glass water resistance, and limit the content of the phosphoric acid (P
2 O
5) which is used as a main component of the near infrared absorbing glass to less than 50 mol%, while of the two alkaline by adjusting the content ratio to a specific range, even if an alkali content increases through the mixed alkali effect eopeumyeonseo the characteristic deterioration of durability such as chemical it has the advantage to prevent the temperature rise of the molten glass.
