PROBLEM TO BE SOLVED : To provide an inspection apparatus of a secondary battery which allows for inspection of internal short circuit of a secondary battery with high accuracy by a simple configuration.SOLUTION : The inspection apparatus of a secondary battery comprises lithium ion secondary batteries 10a...10e, a negative electrode side lead wire 21 which interconnects one electrodes of a plurality of charged lithium ion secondary batteries 10a...10e, and a positive electrode side lead wire 22 which interconnects the other electrodes of a plurality of charged lithium ion secondary batteries 10a...10e via resistors Ra-Re having the same resistance. The inspection apparatus inspects internal short circuit of each charged lithium ion secondary battery 10a...10e based on the potential difference across each charger Ra-Re.
