  "textContent": "A current-carrying component for use in a secondary battery includes a plurality of metal foil members stacked one on top of another in the thickness direction of the metal foil members. Two or more through-holes are formed to extend through the metal foil members in the thickness direction of the plurality of metal foil members. The plurality of metal foil members are welded together by solid-phase welding to form a welded portion, which form a rim surrounding the through-hole. The inner peripheral surface of the welded portion constitutes the inner peripheral surface of the through-hole. A circular ring-shaped protrusion is provided at one end of the welded portion.",
