1. A battery module comprising:
a cell stack including a plurality of battery cells stacked therein;
a bus bar assembly coupled to a side of the cell stack, on which an electrode lead of the battery cell is disposed; and
a sensing device coupled to the bus bar assembly and measuring a temperature of the battery cell,
wherein
the sensing device includes a temperature sensor disposed in contact with the battery cell, and an elastic bracket pressing the temperature sensor to contact with the battery cell through elastic force,
the bus bar assembly is configured to be coupled to the cell stack in a first direction, and
the elastic bracket is configured to press the temperature sensor in a second direction perpendicular to the first direction.
