Abstract
A battery pack has a plurality of series-connected batteries each having an electrode body, a battery case, a positive extending member, a positive external terminal mechanically joined and electrically connected to a positive external extending part of the positive extending member, by caulking deformation thereof, a negative extending member, and a negative external terminal mechanically joined and electrically connected to a negative external extending part of the negative extending member, by caulking deformation thereof. Among the positive and negative external extending parts, the positive and negative external terminals, the metal making up the positive external extending part has the lowest tensile strength. The battery pack includes bus bars; positive fastening members for fastening the positive external terminals to the bus bars; and negative fastening members for fastening the negative external terminals to the bus bars. The negative external terminal is thinner than the positive external terminal.
