1. A pressing jig apparatus for welding, which is installed at one side of a battery module having a cell stack formed by stacking a plurality of battery cells and presses an electrode leads so that the electrode leads are welded in close contact with both sides of a bus bar provided to the battery module, the pressing jig apparatus comprising:
a first frame; and
a second frame coupled to face the first frame and to be rotatable relative to the first frame,
wherein the first frame includes a first pressing tip provided at on longitudinal end thereof and configured to press a first lead group of a first unit cell stack provided in the cell stack so that the first lead group comes into close contact with one side of the bus bar, and
wherein the second frame includes a second pressing tip provided at one longitudinal end thereof to face the first pressing tip and configured to press a second lead group of a second unit cell stack provided in the cell stack so that the second lead group comes into close contact with the other side of the bus bar.
