An electrode includes an electrically non-conductive support. A protruding, electrically conductive attachment element with an attachment site for the releasable attachment of a signal conductor is on an upper face of the support. A conductor is on the underside of the support, and is electrically connected to the attachment element and to a contact medium. The conductor and the contact medium are arranged on the underside of the support. An imaginary normal to the support, running through the attachment element, runs through the conductor or a recess in the conductor and through the contact medium or a recess in the contact medium. The conductor has on its surface a redox pair suitable for the depolarization of the electrode. The attachment element has a projection reaching through the support with a widened region at its end, and the conductor is arranged between the widened region and the support.
