Summary:To provide a light-emitting device capable of preventing reduction in light-emitting efficiency caused by propagation of leakage current to a signal line even in a case that leakage current from a light-emitting element part is generated.SOLUTION: A light-emitting chip comprises: a semiconductor substrate 70; a light-emitting element part formed on the semiconductor substrate, having a plurality of light-emitting elements 40 that emit light; and a signal line 50 formed on the semiconductor substrate and transmitting a signal to the light-emitting elements. An oxide film 81 is formed between the signal line and the semiconductor substrate, along an extending direction of the signal line.SELECTED DRAWING: Figure 4 【課題】発光素子部からの漏れ電流が生じた場合であっても、漏れ電流が信号線に伝わることによる発光効率の低下を防ぐ発光装置を提供する。【解決手段】発光チップは、半導体基板７０と、前記半導体基板上に形成され、光を照射する複数の発光素子４０を有する発光素子部と、前記半導体基板上に形成され、前記発光素子へ信号を伝達する信号線５０と、を備え、前記信号線の延長方向に沿って、前記信号線と前記半導体基板との間に酸化膜８１が形成されている。【選択図】図４
