Zusammenfassung:PROBLEM TO BE SOLVED: To provide an organic EL element and an organic EL lighting apparatus having little angle dependence of a spectrum.SOLUTION: An organic EL element 10 comprises a transparent base material 20, and an organic EL layer 30 disposed on the transparent base material 20 and containing an anode 31, an organic layer 32, and a cathode 33. A waveform pattern 23 is formed on the surface (a light-incidence surface 21) of the transparent base material 20 on the organic EL layer side. As a result, emitted light from the organic layer 32 of the organic EL layer 30 travels to a light-emitting surface 22 of the transparent base material 20 as diffused light, and the angle dependence of a spectrum is reduced in the organic EL element 10.
