To enable the prediction of a battery residual amount with high accuracy in a tire air pressure measuring device and a tire air pressure measurement system.SOLUTION: The tire air pressure measurement system is provided with a tire air pressure measuring device including a battery, a pressure sensor and a temperature sensor which operate by power of the battery, and a voltage monitoring part for monitoring the voltage of the battery. Also, the tire air pressure measurement system is provided with an information processing device including a reception part for receiving information from the tire air pressure measuring device, and an information output part for outputting sound information or display information. Then, the tire air pressure measuring device or the information processing device has a residual amount determination part (step S9) for determining a residual amount of the battery on the basis of the voltage of the battery, and switches the execution and the non-execution of determination of the residual amount on the basis of a physical amount about temperature (step S7).SELECTED DRAWING: Figure 4
