1. A semiconductor light-emitting device comprising:
- 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.
