The invention discloses high-refractive-index glass for a high-transmittance optical fiber image transmitting element and a preparation method of the high-refractive-index glass. The glass is prepared from the following components: 15.0 to 25.0 percent of SiO2, 0 to 0.5 percent of Al2O3, 20.0 to 30.0 percent of B2O3, 1.01 to 2.0 percent of MgO, 1.0 to 5.0 percent of SrO, 15.0 to 25.0 percent of BaO, 0.5 to 2.0 percent of ZnO, 0.1 to 0.2 percent of SnO2, 5.0 to 9.0 percent of TiO2, 1.0 to 5.0 percent of WO3, 5.0 to 10.0 percent of La2O3, 1.0 to 5.0 percent of Nb2O5, 0.5 to 2.0 percent of Y2O3, 1.1 to 5.0 percent of Ta2O5 and 0 to 0.9 percent of Gd2O3. The invention has the advantages of good transmittance, high refractive index and high strain point temperature; filling glass for a fiber optic image-transmitting element. 本发明公开了一种高透过率光纤传像元件用高折射率玻璃及其制备方法，该玻璃由以下组分组成：SiO2 15.0-25.0％，Al2O3 0-0.5％，B2O3 20.0-30.0％，MgO 1.01-2.0％，SrO 1.0-5.0％，BaO 15.0-25.0％，ZnO 0.5-2.0％，SnO2 0.1-0.2％，TiO2 5.0-9.0％，WO3 1.0-5.0％，La2O3 5.
