Provides light-emitting components, light-emitting element array chips, and optical measurement devices. The light-emitting component includes a substrate, and a plurality of light-emitting elements provided on the substrate, emitting light in a direction intersecting with a surface of the substrate, and turning on and off together, the plurality of light-emitting elements having a film thickness ratio of the light-emitting element to the light-emitting element. A gate layer having a thick length of the wavelength of light, and the gate layer performs control to turn on and off the plurality of light-emitting elements together. |
