Abstract
The LED element has a conductive layer formed on the upper layer of the support substrate; a conductive oxide film layer formed on the upper layer of the conductive layer and made of a material having a thermal expansion coefficient of 1×10−6/K or more and 1×10−5/K or less; a light-emitting layer; a third semiconductor layer made of an n-type nitride semiconductor formed on the upper layer of the light-emitting layer; and an electrode formed at a position facing the conductive oxide film layer in a vertical direction so that a bottom surface of the electrode is in contact with a portion of an upper surface of the third semiconductor layer.
