According to one embodiment, a luminaire includes a light-emitting part (110) to emit a blue light with a peak wavelength of 430 nanometers or more and less than 460 nanometers, and a phosphor that is excited by the emitted light of the light-emitting part (110) and emits a light having a color different from blue. In an emission spectrum including the emitted light of the light-emitting part and the light emitted from the phosphor, an intensity peak in a range of a light wavelength of 430 nanometers to 490 nanometers is in a range of a wavelength of 470 nanometers to 490 nanometers. |
