PROBLEM TO BE SOLVED: To suppress current leakage and improve the reliability.SOLUTION: A light-emitting element 100 comprises: a supporting body 101; a low-resistance conductive layer 113 bonded onto the supporting body 101 via a bonding layer 102; a high-resistance conductive layer 112 located on the low-resistance conductive layer 113; an insulating film 110 located on the high-resistance conductive layer 112; and a p-electrode 103 located on the insulating film 110. An opening 114 is opened in the insulating film 110. The high-resistance conductive layer 112 and the p-electrode 103 are bonded with each other via the opening 114. In addition, a first groove 108 is formed on a surface at the p-electrode 103 side, of a p-type layer 104. The first groove 108 has a depth reaching an n-type layer 106. An auxiliary electrode 109 is formed on a bottom face of the groove 108. The first groove 108 is filled with the insulating film 110. The high-resistance conductive layer 112 is made of a conductive material having a resistivity higher than that of the bonding layer 102. |
