PROBLEM TO BE SOLVED: To provide a semiconductor light-emitting device which enhances uniformity of a current in a main semiconductor region which is a light-emitting surface, and has an overvoltage protection element with improved reliability.SOLUTION: The semiconductor light-emitting device, having an overvoltage protective function, comprises: a silicon semiconductor substrate 1; a main semiconductor region for a light emitting element; a first electrode; and a second electrode. The silicon semiconductor substrate has a protection element formation region. The first electrode has a bonding pad electrode 20. An optical transparent conductive film 19 and an insulator film 17, formed in roughly a rectangular or roughly a square shape, are disposed on the main semiconductor region. A hole 17b is formed in the insulator film, and a bonding pad electrode part and the optical transparent conductive film are connected with a band shape connection conductive layer 22, formed so as to include the hole. The hole is so formed as to include at least a center of the bonding pad electrode and a central part of an outer peripheral edge corner of the optical transparent conductive film on a diagonal line of the optical transparent conductive film. |
