摘要： A semiconductor light emitting device includes a semiconductor layer including a light emitting layer, a p-side electrode provided on a second surface of the semiconductor layer, and an n-side electrode provided on the semiconductor layer to be separated from the p-side electrode. The p-side electrode includes a plurality of contact metal selectively provided on the semiconductor layer in contact with the second surface, a transparent film provided on the semiconductor layer in contact with the second surface between the plurality of contact metal, and a reflective metal provided on the contact metal and on the transparent film in contact with the contact metal, the reflective metal including silver. A surface area of a surface of the reflective metal on the light emitting layer side is greater than the sum total of a surface area of the plurality of contact metal contacting the semiconductor layer.
