In semiconductor light emitting sections capable of effectively improving electric cross-talk and effectively avoiding short-circuit between each of light emitting devices, in which a plurality of semiconductor light emitting sections are formed to a semiconductor substrate, and at least one of electrodes for the semiconductor light emitting sections and bonding pads lead out electrically from the electrodes and connected with external leads are formed on one main surface of a semiconductor substrate, a high resistance isolation region is formed, facing the main surface of the semiconductor substrate, below a portion between adjacent conductor layers for electrical leading from the electrode to the bonding pad.
