Summary:An organic light-emitting element having a high light extraction efficiency and a high light emission efficiency is provided, by an organic light-emitting element (10) including: a transparent anode layer (12) formed on a substrate (11); a first penetrating portion (16) formed to penetrate the anode layer (12); a dielectric layer (13) formed to cover an upper surface of the anode layer (12) and an inner surface of the first penetrating portion (16); a second penetrating portion (17) formed to penetrate the anode layer (12) and the dielectric layer (13); an organic compound layer (14) that includes a light emitting layer formed to cover at least an inner surface of the second penetrating portion (17); and a cathode layer (15) formed on the organic compound layer (14), wherein a refractive index of the dielectric layer (13) is lower than a refractive index of the anode layer (12).
