1. A light emitting device comprising:

  • a nitride semiconductor substrate with a resistivity of 0.5 Ω

    ·

    cm or less;

    an n-type nitride semiconductor layer at a first main surface side of said nitride semiconductor substrate and a p-type nitride semiconductor layer placed more distantly from said nitride semiconductor substrate than said n-type nitride semiconductor layer at said first main surface side; and

    a light emitting layer placed between said n-type nitride semiconductor layer and said p-type nitride semiconductor layer at said first main surface side, wherein one of said nitride semiconductor substrate and said p-type nitride semiconductor layer is mounted at the top side which emits light and the other is placed at the down side, and a single electrode is placed at the top side.
