PROBLEM TO BE SOLVED: To provide an organic electroluminescent element of low cost which is flexible and light-weighted, has a long life and high quality, and does not break. SOLUTION: The organic electroluminescent element includes an amorphous positive electrode and a luminescent medium layer containing an organic compound, and the organic compound contained in the luminescent medium layer is oxidized by electron-accepting dopant not containing protonic acid. The organic compound in a periphery of the positive electrode is oxidized by the dopant. Furthermore, the organic compound oxidized by the dopant is a polymer and the dopant is an organic compound or salt of the organic compound.
