1. A bus bar assembly comprising:
a first type frame having a plurality of through-holes including a single through-hole, through which two electrode leads of a plurality of battery cells extend together;
a second type frame having a plurality of through-holes including two through-holes, through which two electrode leads of a plurality of battery cells extend, respectively;
wherein one of the first and second type frame is an assembly frame;
a plurality of sensing bus bars integrally formed on the assembly frame by adding a material constituting the assembly frame to the plurality of sensing bus bars;
an inter bus bar configured to connect any one pair of sensing bus bars, among the plurality of sensing bus bars, to each other, wherein the inter bus is not integrally formed on the assembly frame; and
a terminal bus bar configured to connect any one of the plurality of sensing bus bars to an external terminal, wherein the terminal bus bar is not integrally formed on the assembly frame,
wherein in the first type frame, the single through-hole is formed between any one pair of sensing bus bars, among the plurality of sensing bus bars, and
wherein in the second type frame, the two through-holes are formed between any one pair of sensing bus bars, among the plurality of sensing bus bars.
