A disposable electrode assembly for establishing electrical contact with an underlying skin surface includes a relatively thin transparent base member having a central hub portion and an adhesive-coated undersurface, a conductive gel-impregnated sponge contact contained in a downwardly facing recess located in the hub, and a relatively thick and inflexible cover member coextensive with the base member. In storage the cover member is attached to the undersurface of the base member by the adhesive and the sponge is confined within the recess. Prior to use the base member is peeled away from the cover member to expose the adhesive surface, which when applied to a skin surface holds the sponge contact in compression-contact therewith. The base is transparent to enable the user to detect skin irritation and incomplete adhesion of the base member, and may be provided with apertures to facilitate breathing of the underlying skin. A combined container and dispenser for conveniently storing and dispensing the electrode assemblies is shown.
