SENSING ASSEMBLY AND BATTERY MODULE

The present invention relates to a sensing assembly and a battery module, which can have a relatively small weight, simplify a component assembly process, reduce manufacturing costs, and prevent a sensing leg from being damaged due to an assembly step or an external force. The sensing assembly according to the present invention may comprise: a first substrate having at least one first terminal and at least one second terminal disposed on one surface and formed of a rigid printed circuit board; a second substrate including at least one sensing line electrically connected with the first terminal, and formed of a flexible printed circuit board; and a sensing leg having one end portion electrically connected to the second terminal and including a fuse portion disconnected when an overcurrent flows. 本发明涉及一种感测组件以及电池模块，其可以具有相对小的重量，简化部件组装过程，降低制造成本并且防止感测腿由于组装步骤或外部力而损坏。根据本发明的感测组件可以包括：第一基板，其具有设置在一个表面上的至少一个第一端子和至少一个第二端子，并且由刚性印刷电路板形成；第二基板，其包括与第一端子电连接的至少一条感测线，并且由柔性印刷电路板形成；以及感测腿，其具有电连接到第二端子的一个端部，并且包括当过电流流动时断开连接的熔断器部。
