[Problem] To provide a light-emitting device which, due to excitation by light from a light source, has a peak wavelength in a region exceeding at least 700 nm.[Solution] A light-emitting device comprising a solid-state light source that emits light having a peak wavelength in the range of 480 nm or less and a fluorescent film that covers the solid-state light source and includes at least one kind of phosphor, wherein the fluorescent film includes at least one kind of near-infrared phosphor that is excited by light from the solid-state light source, has a peak wavelength in the range exceeding 700 nm, and has an emission spectrum with a full width at half maximum of 100 nm or more in a range including the peak wavelength. |
