PURPOSE:To make it possible to enhance outer quantum efficiency through a relative reduction in void light emitting under an electrode, and what is more, emit short wavelength light with higher efficiency. CONSTITUTION:An electrode 16, which is installed on the surface 30 of a light emitting diode (semiconductor chip), is provided with a substantially semi- circular-shaped pad portion 18. It is further provided with primary branches 19a to 19d extending linearly from the pad portion 18 and secondary branches 20a, 20b, and 20c extending linearly from each of the primary branches 19a to 19d, and third branches extending linearly from each of the secondary branches 20a, 20b and 20c, at the least. |
