A button cell includes a housing cup and a housing top separated from one another by an insulating seal and which form a housing with a flat bottom and a flat top parallel to it, and an electrode-separator assembly within the housing including flat layer positive and negative electrodes and connected to one another by a flat separator, wherein the layers are aligned essentially at right angles to the flat bottom and the flat top and the electrode-separator assembly is a spiral winding having end faces defining side surfaces of the spiral winding facing in an axial direction relative to the flat bottom and the flat top, and one of the electrodes connects to the flat bottom or the flat top via an output conductor including a thin film resting flat between an end face of the spiral winding and the flat top or the flat bottom.
