Provided are: a glass composition for wound care, which promotes a wound healing process by providing a moist environment and nutrients necessary for growth of epidermal cells, and which has bactericidal properties for preventing critical fixing of bacteria to a wound surface and infection with bacteria and a wound covering material that uses the glass composition. The glass composition contains, by mass % in terms of oxides, 5 to 70% of SiO2, 0 to 10% of Al2O3, 5 to 40.0% of B2O3, and 1 to 50% of CaO.
