Led element and method for producing same

An LED element comprising:

• a substrate;
• a semiconductor lamination part that includes a light-emitting layer formed on a front surface of the substrate;
• a reflecting portion formed on a back surface of the substrate;
• and
• an electrode formed on the semiconductor lamination part, wherein the electrode includes a diffusion electrode layer formed on the semiconductor lamination part and a moth-eye layer which is formed on the diffusion electrode layer and of which the front surface forms the transmissive moth-eye surface having depression parts or projection parts formed with a period smaller than twice the optical wavelength of the light emitted from the light-emitting layer, and
• the moth-eye layer is formed of a material which has a smaller extinction coefficient than a material that forms the diffusion electrode layer with respect to the light emitted from the light-emitting layer and has approximately the same index of refraction as the material that forms the diffusion electrode layer.
