The utility model provides a high-magnification cylinder-shaped super capacitor electric core, which comprises an anode sheet, a cathode sheet, anode lugs, cathode lugs and a diaphragm, wherein anode and cathode current collectors are aluminum foils, the anode and cathode sheets have a plurality of lugs, and after the anode and cathode sheets are wound, the anode and cathode lugs are positioned on the same line for bringing convenience to lug welding. In the electric core, a structure is optimized and the internal resistance of the capacitor is effectively reduced without increasing the manufacturing cost of the capacitor obviously, thereby increasing the magnification performance of the capacitor and having remarkable utility value and economic benefit. The electric core is simple in structure, easy in manufacturing and wide in application scope.
