An organic electroluminescent element 1 according to the present invention includes: a substrate 2; a first electrode 3 formed on the substrate; an organic light-emitting layer 5 formed on the first electrode 3 so as to be brought into contact with the first electrode 3; and a second electrode 6 formed on the organic light-emitting layer 5, characterized in that an ion-doped surface onto which hydrogen ions or hydroxide ions are doped as dopant is provided in the vicinity of a contact interface B between the first electrode 3 and the organic light-emitting layer 5. By such characteristics, an organic electroluminescent element can be obtained, in which a low-voltage drive is made possible, and a long lifetime is realized.
