Abstract
A nitride semiconductor light emitting device comprising an n-side nitride semiconductor layer and a p-side nitride semiconductor layer formed on a substrate, with a light transmitting electrodeformed on the p-side nitride semiconductor layer, and the p-side pad electrodeformed for the connection with an outside circuit, and the n-side pad electrodeformed on the n-side nitride semiconductor layer for the connection with the outside circuit, so as to extract light on the p-side nitride semiconductor layer side, wherein taper angles of end faces of the light transmitting electrodeand/or the p-side nitride semiconductor layer are made different depending on the position.
