Abstract
A sintered phosphor-composite having a high internal quantum efficiency and a high transmittance is provided. The object can be achieved with a sintered phosphor-composite including a nitride phosphor and a fluoride inorganic binder, wherein, in cross-sectional observation, the sintered phosphor-composite includes at least a portion in which voids of not more than 1 μm are present in a number of not more than 700 within a cross-sectional area of 0.046 mm, or a portion having a void area fraction of not more than 3% within a cross-sectional area of 0.046 mm.
