When viewed in the arrangement direction, the cooler includes a first protruding portion that protrudes into the housing case from between the bipolar batteries, and a second protruding portion that protrudes out of the housing case. A weak portion configured to rupture at a pressure lower than a pressure resistance limit of the housing case is provided on each of the first protruding portion and the second protruding portion.",
