Provided is an organic electroluminescent element that can obtain white light with excellent color rendering properties and is particularly suitable for a light source of a lighting device. The organic electroluminescent element includes a plurality of light emitting units that are provided between a cathode and an anode and include at least a light emitting layer made of an organic compound. White light emitted from the plurality of light emitting units has a continuous emission spectrum (S) in a wavelength range of at least 380 nm to 780 nm. The emission spectrum (S) includes one peak wavelength (p) in a red wavelength range (R) of 600 nm to 640 nm, one peak wavelength (p) in a green wavelength range G of 500 nm to 540 nm, and two peak wavelengths (p) and (p) in a blue wavelength range B of 440 nm to 490 nm.
