A stimulation device for transcutaneous electric stimulation stimulus onto the surface of a section of the human ear comprises a holding element attached at or in the ear and at least two electrodes arranged in or at an electrode carrier, wherein the at least two electrodes are separated from another at the electrode carrier by an electrically isolating section. To obtain a good electrical conductibility of the electrodes at high ear comfort, the at least two electrodes are covered by a casing element, the casing element comprises at least two cover elements, wherein each of the at least two cover elements comprises a retaining region for an electrode； the material of the cover elements is electrically conductive or can be made electrically conductive； the casing element comprises at least one isolation section made of electrically isolating material； the isolating section connects at least two cover elements with another.
