    摘要: In a lithium-ion secondary battery (100), a battery case (300) has sidewalls (300A, 300B) facing toward side ends of a wound electrode body (200), the side ends being at opposite lateral sides of the positive electrode sheet (220), and of the sidewalls (300A, 300B), one of the sidewalls (300A) (positive-electrode-side sidewall) facing toward an uncoated portion (222) of the positive electrode sheet (220) is thicker than the other sidewall (300B) (negative-electrode-side sidewall). In other words, the relationship between the thickness A of the one sidewall (300A) facing toward the uncoated portion (222) of the positive electrode sheet (220) and the thickness B of the other sidewall (300B) is A>B.
