Abstract
A nitride semiconductor laser device includes, on a first principle face of the (0001) of a nitride semiconductor substrate, a nitride semiconductor layer having a first conductivity type, an active layer, and a nitride semiconductor layer having a second conductivity type that is different from the first conductivity type, and being formed a stripe ridge on the surface thereof. The (000-1) face and an inclined face other than the (000-1) face are exposed on a second principal face of the nitride semiconductor substrate. The inclined face other than the (000-1) face represents no less than 0.5% over the surface area of the second principal face.
