Phosphate glass, optical glass, and optical element

The invention provides a phosphate glass and an optical glass, and an optical element using the optical glass, wherein the phosphate glass has good transmittance before heat treatment, high productivity, and excellent transmittance in a wide visible light region including short wavelengths, and has a high refractive index region. The phosphate glass has a refractive index (nd) of 1.90000 or more and a spectral transmittance ([lambda] 5) of 400 nm or less, contains more than 0% and less than 1.0% of a Li2O component in terms of mass% based on oxides, and has a mass sum of WO3 + Bi2O3 + Gd2O3 of 10.0% or less. 本发明提供一种热处理前的透射率良好，并且生产率高、在包括短波长的较宽的可见光区域的透射率优良的高折射率区域的磷酸盐玻璃以及光学玻璃，以及使用该光学玻璃的光学元件。该磷酸盐玻璃，其折射率(nd)为1.90000以上，分光透射率(λ5)为400nm以下，以氧化物基准的质量％计，含有大于0％且小于1.0％的Li2O成分，质量和WO3+Bi2O3+Gd2O3为10.0％以下。
