Abstract
A circuit board apparatus of a battery pack in which tape is attached to low priced flexible printed circuit boards (FPCB) so that it is possible to prevent cracks from being generated in the FPCBs when the FPCBs are bent. The circuit board apparatus includes a first board, a second board, and a bendable third board with one side electrically connected to one side of the first board, and the other side electrically connected to one side of the second board. The first board is oblique to the second board, or the first board is substantially perpendicular to the second board. Protective tape is provided on a first region where the first board and the third board overlap, and in a second region where the second board and the third board overlap.
