1. A light-emitting component comprising:
a substrate;
a plurality of light-emitting elements that are disposed on the substrate and that emit light in a direction intersecting with a surface of the substrate; and
a plurality of thyristors that are stacked on the plurality of 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,
wherein each of the plurality of light-emitting elements includes a current confinement region which is oxidized via a plurality of holes provided in a multilayer structure, the multilayer structure being constituted by a corresponding light-emitting element and a corresponding thyristor,
the plurality of thyristors is stacked on the plurality of light-emitting elements via a tunnel junction layer,
the plurality of holes does not reduce the area of the tunnel junction layer in a plan view compared to a case that the corresponding light-emitting element and the corresponding thyristor are formed in a cylindrical shape.
