A light-emitting device capable of suppressing melatonin secretion is provided. A light emitting device according to an embodiment includes a light emitting element that emits light having a peak wavelength of 420 nm to 445 nm, a first phosphor that emits light having a peak wavelength of 485 nm to less than 530 nm, and a peak of 530 nm to less than 580 nm. A second phosphor that emits light having a wavelength and a third phosphor that emits light having a peak wavelength of not less than 600 nm and less than 650 nm, emits light having a color temperature of not less than 4600K and not more than 5400K, and has an emission spectrum of light The light intensity has a minimum value at a wavelength of 450 nm or more and 470 nm or less, and the minimum value is 60% or less of the maximum light intensity on the long wavelength side from the minimum value.
