PURPOSE: A tire air pressure sensor module of a tire air pressure monitoring system is provided to reduce vibration and energy consumption due to a metal antenna by using a flexible antenna. CONSTITUTION: A tire air pressure sensor module of a tire air pressure monitoring system comprises a PCB(printed circuit board), a flexible antenna, a case, and a PCB box. The PCB comprises a sensor for temperature and air pressure. The flexible antenna is connected to the PCB and transfers measured information wirelessly. The flexible antenna is mounted on the case. The case is connected to the PCB and the flexible antenna. The case comprises a tap joint(11a). The tap joint is coupled with an air tap(40). The air tap is connected to the inner space of a tire.
