1. 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 the plurality of terminal parts and the at least one temperature sensing part branched from the main able are short circuited to each other, and
wherein the temperature sensing part is proximal to the connecting part and the terminal parts are distal to the connecting part in the main cable.
