An abnormality diagnosis device includes: a measurement unit (cell voltage measurement unit (202)) for measuring the state of a device to be diagnosed (battery cell); a first abnormality determination unit (overvoltage and over-discharge determination unit (203)) for determining the abnormality of the device to be diagnosed on the basis of the measurement results; and a second abnormality determination unit (main processing unit (301)) for similarly determining the abnormality of the device to be diagnosed on the basis of the measurement results. The measurement unit (202) and the first abnormality determination unit (203) are provided on a first substrate (cell state measurement unit (101)), while the second abnormality determination unit (301) is provided on a second substrate (cell state calculation unit) different from the first substrate, so that the failure rate due to a common failure factor (substrate) is reduced.
