Disclosed is a semiconductor light-emitting device including a package having a light outlet, a semiconductor laser diode disposed in the package and radiating a light having a first wavelength falling within a range of ultraviolet ray to visible light, and a visible-light-emitter containing a phosphor which absorbs a light radiated from the semiconductor laser diode and emits a visible light having a second wavelength differing from the first wavelength, the visible-light-emitter being disposed on an optical path of the laser diode and a peripheral edge of the visible-light-emitter being in contact with the package.
