Abstract:
An alignment inspection apparatus for the electrode assembly including a laminate, in which a first separator, an internal electrode, a second separator, and an upper electrode are sequentially laminated, includes a camera disposed above a central portion of the electrode assembly to photograph and inspect the electrode assembly and side lights obliquely irradiating light onto each of both ends of the upper electrode. The side lights are symmetrical to each other with respect to the central portion of the electrode assembly.
