It is an object of the present invention to provide a light-emitting element having, between a pair of electrodes, a layer containing a light-emitting material and a transparent conductive film, wherein the electric erosion of the transparent conductive film and reflective metal can be prevented and to provide a light-emitting device using the light-emitting element. According to the present invention, a first layer 102 containing a light-emitting material, a second layer 103 containing an N-type semiconductor, a third layer 104 including a transparent conductive film, and a fourth layer 105 containing a hole-transporting medium are provided between an anode 101 and a cathode 106, wherein the first layer 102, the second layer 103, the third layer 104, the fourth layer 105, and the cathode 106 are provided in order, and wherein the cathode has a layer containing reflective metal.
