The invention relates to an electrode arrangement (1) for applying a transcutaneous electrical stimulus to the surface of a portion of the human ear (2), which comprises a holding element (3) at or in the ear (2) and at least one electrode (4, 5) arranged in or on an electrode support (6). The holding element (3) has a linear guide (7) in which a holding rod (8) is arranged in a linearly displaceable manner in the direction of a longitudinal axis (L) of the holding element (3), wherein the electrode support (6) is arranged on the holding rod (8). In order to achieve an improved transcutaneous stimulation, the invention provides that the electrode support (6) comprises at least one support portion (9) on which the electrode (4, 5) is arranged, wherein the electrode (4, 5) has at least one cylindrical (10) and/or spherical segment-shaped (11) and/or conical surface portion.
