Provided is a glass that has a high refractive index and high liquid phase viscosity without including a large amount of expensive rare earth oxides or the like. This glass with a high refractive index is characterized by having a glass composition containing, by mass%, 30.5-80% of SiO2+Al2O3+B2O3, 10-60% of MgO+CaO+SrO+BaO+ZnO, 4-40% of BaO, 0-20% of TiO2+ZrO2, and 0.01-15% of P2O5, and by having a refractive index (nd) of 1.55-2.00.
