Sensing Assembly and Battery Module

The present invention relates to a sensing assembly and a battery module that may have a relatively low weight, simplify a component assembly process, reduce manufacturing cost, and prevent a sensing leg from being damaged due to an assembly step or an external force. The sensing assembly may include a first substrate having at least one first terminal and at least one second terminal provided on one surface and formed of a rigid printed circuit board, a second substrate including at least one sensing line electrically connected to the first terminal and formed of a flexible printed circuit board, and a sensing leg having one end electrically connected to the second terminal and including a fuse part that is disconnected when an excessive current flows.
