Provided is a wavelength conversion member in which a decrease in light emission intensity over time is small when an LED or LD light is irradiated, and a light emitting device using the same. Wherein the glass matrix contains 30 to 85% of SiO 2 , 4.3 to 20% of B 2 O 3 , 0 to 25% of Al 2 O 3 , Li 2 O 0 to 3%, Na 2 O 0 to 3%, K 2 O 0 to 3%, Li 2 O + Na 2 O + K 2 O 0 to 3%, MgO 0 to 35%, CaO 0 to 35% Wherein the inorganic phosphor contains 0 to 35% of SrO, 0 to 35% of BaO, 0.1 to 45% of MgO + CaO + SrO + BaO, and 0 to 5% of ZnO, wherein the inorganic phosphor is at least one selected from the group consisting of an oxide phosphor, a nitride phosphor, an oxynitride phosphor, Wherein the phosphor is at least one selected from the group consisting of phosphors, acid chloride phosphors, halide phosphors, aluminate phosphors, and halophosphorous chloride phosphors. |
