A phosphor-dispersed glass according to the present invention is a phosphor-dispersed glass in which phosphor particles are dispersed in a glass, said phosphor-dispersed glass being characterized in that the glass contains 1 to 40 mass% of SiO2, 15 to 65 mass% of B2O3, 1 to 50 mass% of ZnO, 0 to 40 mass% of RO (the sum total of the contents of one or more compounds independently selected from the group consisting of MgO, CaO, SrO and BaO), 0 to 30 mass% of R2O (the total content of one or more compounds independently selected from the group consisting of Li2O, Na2O and K2O), and 0 to 5 mass% of ZrO2 (wherein the total content of SiO2, B2O3, ZnO, RO, R2O and ZrO2 is 80 mass% or more). |
