PURPOSE: Provided is a battery package which can mount a case and a FPCB(flexible printed circuit board) easily in the inside of a battery case by changing the form of connection leads of the FPCB. CONSTITUTION: The battery package contains: an electrode assembly having a cathode lead and an anode lead; the case(110) covering and sealing the electrode assembly and having joint parts(112) formed around the upper and lower faces of the case(110), wherein the joint parts(112) are jointed with each other and folded and adhered closely to the side of the case(110); the FPCB(130) laminated on the upper or lower side of the case(110), which contains the connection leads(131, 135) for connecting to electrode leads(103, 105) of the electrode assembly, wherein the connection leads(131, 135) have a stair shape by forming first extension parts(132, 136) extended in the extension direction of the electrode leads(103, 105), second extension parts(133, 137) extended vertically to the first extension parts(132, 136), and third extension part(134, 138) extended vertically to the second extension parts(133, 137); the battery case in which the case(110) and the FPCB(130) are inserted.
