There is provided an antibacterial property imparting glass composition which has high antibacterial durability at a small added amount. An antibacterial property imparting glass composition comprises 0.1-5.0% by weight of Ag2O contained in a glass composition containing 30-60 mol% of P2O5, 2-40 mol% of B2O3, and 1-50 mol% of 1 or 2 or more selected from MgO, CaO and ZnO (water-resistance imparting component). In such the antibacterial property imparting glass composition, a water-resistance imparting component is contained in a glass composition at an amount of 1-50 mol%, it is possible to improve water-resistance while maintaining antibacterial imparting effect to the previous extent at a small amount to be added to a subject material to which antibacterial property should be added and, detergent-resistance is sufficiently retained and, in particular, sustained antibacterial effect is exerted in places of water circumstance such as a kitchen, a bath, a toilet and the like. |
