Abstract: A battery pack includes battery cells arranged in a first direction, a wiring board collecting state information about the battery cells, and a sensing portion including an input port through which the state information about the battery cells is input, an output port coupled to the wiring board and through which the state information about the battery cells is output, and a connection portion between the input and output ports. The connection portion extends in a curved shape with portions spaced apart from each other in a second direction crossing the first direction. Damage or dielectric breakdown of a conductive line transmitting signals relating to the state information about the battery cells may be prevented, and accumulation of stress in the conductive line or an insulating film may be prevented, because the conductive line or the insulating film is flexibly deformed in response to swelling of the battery cells.
