Abstract
A light-emitting component includes: plural transfer thyristors each configured with a semiconductor layer stack laminating first to fourth semiconductor layers, and shifting to an ON state in order; plural coupling transistors each configured with the first to third semiconductor layers, provided to couple adjacent transfer thyristors, the first and the second semiconductor layers of the coupling transistor being continued to the first and the second semiconductor layers of the former transfer thyristor; plural first resistances, each provided between the third semiconductor layer of each transfer thyristor and a wiring for power supply; a second resistance having a resistance value smaller than a product of a resistance value of the first resistance and a ratio of a collector current of the coupling transistor to a cathode current of the transfer thyristor in the ON state; and plural light-emitting thyristors each configured with the semiconductor layer stack.
