Provided are: a glass composition for wound healing, said composition promoting a wound healing process by providing the moist environment and nutrients required for growth of epidermal cells, and having bactericidal properties for preventing the critical fixing of bacteria to a wound surface and infection with said bacteria； and a wound covering material that uses said glass composition. The glass composition is characterized by containing, by mass% in terms of oxides, 5-70% of SiO 2 , 0-10% of Al 2 O 3 , 5-40.0% of B 2 O 3 , and 1-50% of CaO.
