A multi-wavelength light-emitting element (100) is provided with: a first semiconductor light-emitting layer (151) that is formed by having a semiconductor crystal-grown on a first semiconductor layer (131) formed on a substrate (110); and a second semiconductor light-emitting layer (152) that is formed by having a semiconductor crystal-grown on a second semiconductor layer (132) formed on the substrate (110), and that emits light with a wavelength different from the wavelength of light emitted by the first semiconductor light-emitting layer (151). |
