1. A battery module having a cell-unit monitoring structure, comprising:
a battery cell stack formed by stacking a plurality of battery cells sealed by an individual cell pouch;
a case configured to cover the battery cell stack through an assembly structure of a plurality of plates; and
a sensing block comprising an interface module configured to measure a sensing signal by electrically connecting the individual cell pouch and battery cell electrode tabs exposed through the front side and the rear side of the case,
wherein the interface module comprises:
a printed circuit board (PCB) connector unit configured to communicate with a controller of an external system;
a plurality of busbars electrically connected to the electrode tabs exposed from the battery cell and configured to sense voltage information;
a first sensing lead line configured to connect the plurality of busbars and the PCB connector unit; and
a pouch contact probe configured to physically contact the individual cell pouch and a second sensing lead line configured to electrically connect the individual cell pouch and the PCB connector unit.
