A method of manufacturing a glass-phosphor composite is disclosed. The method comprises : preparing rare earth ion-containing parent glass; mixing the rare-earth ion-containing parent glass in a power state with a phosphor in a powder state; and providing a glass-phosphor composite using the powder mixture of the rare earth ion-containing parent glass and the phosphor, wherein the mixing includes mixing the rare earth ion-containing parent glass in the powder state with the phosphor in the powder state so that the phosphor in the glass-phosphor composite is in an amount of 5 wt % to 30 wt %, and the preparing includes using a glass frit having a glass transition point of 300° C. to 800° C. and a sintering temperature of 200° C. to 600° C.
