PURPOSE: An RFID(Radio Frequency Identification) antenna built-in battery pack is provided to form a flex-suppressor between a battery cell and an RFID antenna, in order to cut off an electric wave output from an RFID reader, thereby preventing the electric wave from being absorbed into the battery cell. CONSTITUTION: A battery pack(100) comprises as follows. A battery cell(110) charges and discharges power to be supplied to a terminal body, and has a power terminal. A flex-suppressor(120) is located in an upper part of the battery cell(110), and removes an electric wave or noise. An RFID antenna(130) is located in an upper part of the flex-suppressor(120), and receives an induced electromotive force by power of an RF reader, then performs wireless communication with the RF reader. The RFID antenna(130) is a loop-type antenna or a micro strip line antenna.
