Abstract
There is provided a semiconductor light-emitting device including a semiconductor light-emitting element, a phosphor layer disposed in a light path of a light emitted from the semiconductor light-emitting element, containing a phosphor to be excited by the light and having a cross-section in a region of a diameter which is 1 mm larger than that of a cross-section of the light path, and a heat-releasing member disposed in contact with at least a portion of the phosphor layer and exhibiting a higher thermal conductance than that of the phosphor layer.
