To provide a light-emitting device which is configured to emit light while switching among multiple light-emitting units, and which allows for reducing the distance between the light-emitting units and a drive unit compared with a case where a switching unit for switching among the light-emitting units is provided between the light-emitting units and the drive unit.SOLUTION: A light-emitting device is provided, comprising multiple light-emitting units, a drive unit for driving the light-emitting units by supplying electric current to the light-emitting units, and a switching unit provided on a side opposite the drive unit with respect to the multiple light-emitting units and configured to switch emission among the multiple light-emitting units.SELECTED DRAWING: Figure 5 【課題】複数の発光部を切り替えて発光させる発光装置において、発光部と駆動部との間に発光部を切り替える切替部を設ける場合に比べ、発光部と駆動部との距離を短くできる発光装置などを提供する。【解決手段】発光装置は、複数の発光部と、発光部に電流を供給して発光部を駆動する駆動部と、複数の発光部に対し駆動部とは反対側に設けられ、複数の発光部の発光を切り替える切替部とを備える。【選択図】図５
