Abstract: An antibacterial glass composite, a method of manufacturing antibacterial glass powder using an antibacterial glass composite, and a home appliance including an antibacterial glass composite. The antibacterial glass composition secures antibacterial activity and water resistance at the same time using a content ratio of a modified oxide and a network-forming oxide. As a result, as the antibacterial glass composition, the method for preparing the antibacterial glass power, and the household electrical appliance comprising the antibacterial glass composite use antimicrobial having non-elution characteristics, remarkable effects may be exhibited in preventing bacterial or mold contamination when used as a coating agent on a component element that is in contract with drinking water.
