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.

A drawing sectionfor electric wiresis formed such that a bottom plateand a side wallof a wiring pathare extended to be projected from an insulating plate. A tongue piecearound which a tape is wound together with the wires, is formed on the drawing section. The tongue pieceis bent in a direction opposite to a rising direction of the side wallof the drawing sectionso that a projection dimension of the tongue pieceis reduced.
