Abstract:
An anode lead (20) is bonded between a winding start side end (42a) of an anode mixture layer (42) and a winding finish side end (42b) of the anode mixture layer (42) in an α direction of an electrode (11). When a position opposite to an anode start end is defined as a first position (A) and the center position of a portion opposite to the anode lead (20) is defined as a second position (B) in a cathode mixture layer (52) in a γ direction of a cathode (12), a cathode lead (21) is bonded between the first position (A) and the second position (B) with respect to the γ direction of the cathode (12).
