An assembled battery (10) provided by this invention has a plurality of secondary batteries (2) connected in series, and has a first bypass circuit (12) including a Zener diode (6) connected in parallel so that the connection is in the inverse direction during charging with respect to the series connections, and a second bypass circuit (14) including a varistor (4) connected in parallel to the secondary batteries (2) and the Zener diode (6). The Zener voltage of the Zener diode (6) is set to a prescribed first voltage value, and the varistor voltage of the varistor (4) is set to a second voltage value equal to or greater than the first voltage value. |
