Abstract
Provided is a high refractive index glass, comprising, as a glass composition in terms of mass %, 0.1 to 60% of SiO+AlO+BO, having a mass ratio (BaO+LaO+NbO+TiO+ZrO)/(SiO+AlO+BO) of 0.1 to 50, amass ratio (MgO+CaO+SrO+BaO)/(BaO+LaO+NbO+TiO+ZrO) of 0 to 10, and a mass ratio (TiO+ZrO)/(BaO+LaO+NbO) of 0.001 to 40, and having a refractive index nd of 1.55 to 2.3.
