A semiconductor light emitting device comprises: a semiconductor laminated body; an electrode provided on the first major surface of the semiconductor laminated body; and a reflecting layer provided on the second major surface side of the semiconductor laminated body. The semiconductor laminated body includes a light emitting layer and having a first major surface and a second major surface located on the opposite side of the first major surface. A light emitted from the light emitting layer is extracted from the first major surface. The reflecting layer is conductive and reflective of the light emitted from the light emitting layer. At least a portion of the reflecting layer, which is opposed to the electrode, has irregularities.
