Disclosed is a wavelength conversion member with little decrease in light emission intensity over time when irradiated with light from an LED or LD, and a light emitting device using the same. A wavelength conversion member 2 in which an inorganic phosphor is dispersed in a glass matrix, wherein the glass matrix is mol%, SiO 2 : 30 to 85%, B 2 O 3 : 4.3. 20%, Al 2 O 3: 0~25%, Li 2 O: 0~3%, Na 2 O: 0~3%, K 2 O: 0~3%, Li 2 O + Na 2 O + K 2 O: 0~ 3%, MgO: 0-35%, CaO: 0-35%, SrO: 0-35%, BaO: 0-35%, MgO + CaO + SrO + BaO: 0.1-45%, and ZnO: 0-5% The inorganic phosphor is an oxide phosphor, nitride phosphor, oxynitride phosphor, chloride phosphor, acid chloride phosphor, halide phosphor, aluminate phosphor and halophosphate fluorescence. The wavelength conversion member 2 which is 1 type selected from the group which consists of bodies. [Selection] Figure 1 |
