摘要： A semiconductor optical device includes: a buried layer having a side surface, an upper surface, and an intermediate region; an insulating film on the upper surface of the buried layer; and an electrode including a mesa electrode, a pad electrode, and a lead-out electrode. The upper surface of the buried layer has an outer edge including a first edge extending along the first direction and a second edge extending along a second direction. The intermediate region includes an upright surface that stands straight between the side surface and the first edge, and a slope surface that slopes more gently than the upright surface and extends downward from the second edge. The lead-out electrode includes a portion on the insulating film and connected to the pad electrode, another portion on the intermediate region and through the slope surface, and another portion connected to the mesa electrode.
