A semiconductor light emitting device includes: a substrate; a laminate structure including a first semiconductor layer, an active layer, and a second semiconductor layer; and a current confinement part for limiting a current injection region of the active layer in the second semiconductor layer, or between the active layer and the second semiconductor layer, on the substrate, wherein the current confinement part includes a current confinement layer having a conductive region corresponding to the current injection region of the active layer and a nonconductive region corresponding to a region other than the current injection region of the active layer, and an intermediate layer provided between the current confinement layer and the second semiconductor layer or the active layer in order to prevent a mixed crystal from being formed between the current confinement layer and the second semiconductor layer or the active layer.
