Abstract: A light-emitting component includes: a substrate; plural light-emitting elements that are disposed on the substrate and that emit light in a direction intersecting with a surface of the substrate; and plural thyristors that are stacked on the plural light-emitting elements and that are turned ON to drive the corresponding light-emitting elements so that the light-emitting elements emit light or an amount of light emitted from the light-emitting elements is increased. Each of the plural light-emitting elements includes a current confinement region which is oxidized via a hole provided in a multilayer structure. The multilayer structure is constituted by a corresponding light-emitting element and a corresponding thyristor.
