Interconnecting member occupying less space in battery module and battery module comprising same

An interconnection member for connecting bus bars which are coupled to a printed circuit board (PCB) of a battery module and electrode terminals of battery cells, the interconnection member comprising:

• (a) a main cable made of a flexible flat cable (FFC) including a plurality of wires;
• (b) a plurality of terminal parts branched from the main cable and electrically connected to at least one wire of the plurality of wires of the main cable, the plurality of terminal parts being connected to the bus bars to sense voltages of the battery cells;
• (c) a connecting part formed on one-side end of the main cable, and electrically and mechanically connected to the PCB;
• and
• (d) at least one temperature sensing part branched from the main cable, adjacent to the connecting part, while sharing the at least one wire of the plurality of wires of the main cable,
• wherein at least two of (b) to (d) are made of an FFC,
• wherein the at least one temperature sensing part comprises:
• a first extending part extending from the main cable while sharing the at least one wire of the plurality of wires of the main cable;
• and
• a ceramic thermistor disposed on an end of the first extending part while being electrically connected to the first extending part,
• wherein each of the plurality of terminal parts comprises:
• a second extending part that extends from the main cable;
• and
• a contact part that is electrically connected to the second extending part and contacts a voltage sensing terminal provided in the bus bars.
