The present invention provides an antibacterial glass which can contain an antibacterial metal at a very high content and has improved durability by increasing chemical durability. A and the SiO 2 35-62 mole%, and 6-20 mol% of Al 2 O 3, the B 2 O 3 and 5 to 30 mol%, and 7-20 mol% of Na 2 O, K and 0 to 15 mol% of 2 O, the glass material containing 15 mol% of MgO, by ion exchange treatment, an antimicrobial metal introduced antimicrobial glass, the amount of base metal dissolution are 10ppm or less, The antibacterial activity value after the water resistance test category 3 is 2 or more.
