Abstract
A fluorescent module includes a fluorescent member including a phosphor-containing layer, and a light reflecting layer disposed on the phosphor-containing layer. The phosphor-containing layer contains a YAG phosphor and a Ga-YAG phosphor within the same layer, the Ga-YAG phosphor being a phosphor in which a portion of the aluminum constituting the YAG phosphor is substituted with gallium. A volumetric ratio of the Ga-YAG phosphor to the entirety of the YAG phosphor and the Ga-YAG phosphor is in a range of 19.0% to 80%.
