Abstract: An electrode structure containing plural electrode elements each comprising an electrode and an electrolyte layer laminated thereon, the electrode of each electrode element being connected to a power supply and the electrolyte layer to be in contact with the skin, wherein the plural electrode elements are insulated from each other and the electrode of each element is electrically connected to a resistor that limits the current flowing through this electrode, the resistor having a resistance that is ⅕-5 times the resistance of the skin. The present invention provides an electrode structure capable of making the density of the current flowing to the skin constant, irrespective of the electrification method, and capable of reducing irritation due to the electrification.
