The invention relates to a process for bending a composite busbar, comprising the following steps: (1) disposing long slotted holes on conductive layers in the bending and shaping position of the composite busbar, wherein the size of each long slotted holes is more than the length of an circular arc edge in the bending and shaping part of the composite busbar; (2) flat overlapping and pressing the insulating layer 1, the adhering layer 1, the negative conducting layer, the adhering layer 2, the insulating layer 2, the adhering layer 3, the positive conducting layer, the adhering layer 4 and the insulating layer 3 of the composite busbar; and (3) bending and shaping the flat overlapped and pressed composite busbar by preventing the circular arc edge of an opening from approaching the bending and shaping position of the composite busbar. The process for bending the composite busbar can ensure that the circular arc edge can not deform in the composite busbar shaping process so as to effectively ensure the bending degree of the composite busbar after conducts are combined, the more compact structure of the composite busbar and the utilization of the space of the composite busbar.
