A switching board having switching elements for temperature measurement mounted on a printed circuit board (PCB) having a circuit electrically connected to a unit cell constituting a battery module, the switching board comprising:
- an upper board having a pair of switching elements, a temperature detection element, and one or more vertical through holes, the switching elements being electrically connected to the circuit, the temperature detection element and the vertical through holes being disposed between the switching elements;
- and
- a lower board having a heating pad at a position corresponding to the vertical through holes and the temperature detection element,
- wherein the heating pad is configured to sense heat generated from the switching elements and to transmit the sensed heat to the temperature detection element.
