A battery pack includes a battery assembly having a plurality of battery cells, a busbar module that includes a plurality of conductors and an insulating member which holds the conductors, a battery control unit provided at an end portion of the battery assembly in an arrangement direction of the battery cells, and an extraction conductor that connects a total electrode terminal connected to the battery assembly to a main circuit terminal of the battery control unit. The extraction conductor has a water escape portion which is located below an imaginary line connecting the total electrode terminal to the main circuit terminal, and an upper end of the water escape portion is formed at a location that is lower than a lower end of the main circuit terminal.
