A spirally-wound lithium battery includes: a bottomed cylindrical cell can doubling as an anode current collector; and a strip-shaped electrode body including an anode and a cathode arranged faced each other via a separator, the anode including an anode active material of lithium metal or alloy, the cell can being sealed, with a non-aqueous organic electrolyte, containing the electrode body wound in a longitudinal direction, the electrode body being wound from a winding axis side around the axis in a vertical direction, an extending direction of a cell can cylindrical axis, such that the anode is arranged at an outermost circumference, the electrode body is attached with a conductor, continuously extending in the longitudinal direction thereof, on an outer circumferential surface of the anode, from a winding end of the anode to an area thereof opposed to an inner surface of the cathode on its winding end side.
