The phosphors included in the wavelength converterare substantially composed of Ce-activated phosphors. The above-described light-emitting device includes at least a warm-color Ce-activated phosphor that receives the laser light and radiates light having a light emission peak within a wavelength range of 580 nm or more to less than 660 nm, and light-emitting components radiated by the phosphors are composed of only light-emitting components derived from Ce.
