Inspection method and inspection apparatus for wound cell

An inspection method includes obtaining an image of a corner region of the wound cell that includes an image of a cathode electrode plate at N layers of the corner region of the wound cell and an anode electrode plate at the N layers, and determining, based on the image of the corner region, amounts of misalignment between the cathode electrode plate and the anode electrode plate that are adjacent in the wound cell. N is a positive integer.
