Abstract: PURPOSE: To obtain a light-emitting nitride semiconductor element which lowers a Vf (a forward voltage) by a method wherein a p-type layer forming a positive electrode is constituted of a heavily acceptor-doped first p-type layer and a lightly doped second p-type layer. CONSTITUTION: A contact layer is constituted of a first p-type contact layer 71 in which a layer coming into contact with a positive electrode 9 is formed as a heavily acceptor-doped first nitride semiconductor layer and a second p-type contact layer 72 as a second nitride semiconductor layer acceptor-doped more lightly than the first p-type contact layer. The acceptor concentration of the first heavily doped p-type contact layer is adjusted to 1×10<17> to 5×10<21> /cm<3> . The acceptor concentration of the second lightly doped p-type contact layer 2 is adjusted to a range of 2×10<15> to 5×10<20> /cm<3> . The contact layer 71, 72 form the positive electrode 9, and they are layers which can form desirable ohmic contacts with the positive electrode 9. The closer they are perfect ohmic contacts, the more the Vf of a light-emitting element can be lowered.
