Claim 0:
1. A wavelength conversion member formed of an inorganic phosphor dispersed in a glass matrix, wherein
the glass matrix contains, in % by mole, 30 to 85% SiO2, 0 to 20% B2O3, 0 to 25% Al2O3, 0 to 3% Li2O, 0 to 3% Na2O, 0 to 3% K2O, 0 to 3% Li2O+Na2O+K2O, 0 to 35% MgO, 0 to 35% CaO, 0 to 35% SrO, 0 to 35% BaO, 0.1 to 45% MgO+CaO+SrO+BaO, and 0 to 4% ZnO,
the glass matrix has a softening point of 829 to 1100° C., and
the inorganic phosphor is at least one selected from the group consisting of an oxide phosphor, a nitride phosphor, an oxynitride phosphor, a chloride phosphor, an oxychloride phosphor, a halide phosphor, an aluminate phosphor, and a halophosphate phosphor.
