Abstract: A battery measurement system includes: a battery including terminals and a housing case, and a battery measurement device. The battery measurement device includes: a signal control unit provided on a first electrical path connecting positive and negative electrode external terminals and configured to receive or apply an AC signal, a response signal input unit provided on a second electrical path connecting positive and negative electrodes of an electrode body and configured to receive a response signal to the AC signal, and a calculation unit configured to calculate complex impedance information based on the response signal. The second electrical path is wired from the response signal input unit toward the inside of the housing case so that a magnetic flux passage area surrounded by the electrode body and the second electrical path is smaller in magnitude than an area surrounded by the electrode body, the terminals and the housing case.
