Abstract
A fluorescence light emitting element includes a phosphor layer that includes phosphors and a binder made of an inorganic material. A thermal conductivity B of the binder is larger than 1.88 times a thermal conductivity A of the phosphors. When the volume of the phosphors included in the phosphor layer is X and the volume of the binder included in the phosphor layer is Y, a relationship of X/Y>1/2 is satisfied.
