In a light emitting device, a second electrode is provided over a ridge portion, the ridge portion has a constant width when viewed from a stacking direction of an active layer and a first cladding layer, a second cladding layer includes an electrical connection region that is electrically connected to the second electrode, the active layer constitutes a light waveguide through which light is guided in a region overlapping the ridge portion when viewed from the stacking direction, the light waveguide is provided with a first light emission surface and a second light emission surface from which light is emitted, and, when viewed from the stacking direction, a width of the electrical connection region at a central position whose distances to the first light emission surface and the second light emission surface are the same as each other is smaller than a width of an end of the electrical connection region in an extending direction of the light waveguide. |
