Abstract: A flexible surface electrode for use in carrying current to and from the skin of a human body includes an insulating carrier having a projecting tongue and at least one electrically conductive foil on one side of the carrier and extending along the tongue. The tongue is bent around an end edge of a plate-shaped stiffening member with the foil facing outwardly and away from the end edge of the stiffening member. A clamping plate clamps an end portion of the tongue against the stiffening member, with the foil still being exposed at the end edge thereof. A cover plate covers that portion of the tongue extending from the end edge of the stiffening member toward the remainder of the carrier and the electrode.
