1. An output control method for adjusting an output of a radio communication module including a first antenna comprising:
setting a temperature of the radio communication module to a predetermined set temperature by a temperature adjustor that adjusts the temperature of the radio communication module,
having the first antenna transmit a radio signal by sending a transmission signal of a predetermined frequency in the radio communication module,
controlling an output of the transmission signal based on a comparative result between a power value obtained by detecting the transmission signal and a predetermined threshold value of power,
receiving the radio signal by a second antenna that is capable of radio communicating with the first antenna, and measuring an equivalent isotropic radiated power of the radio signal, and
adjusting an output of the transmission signal based on the measured equivalent isotropic radiated power, wherein
a first gain value is calculated based on a difference between the power value at a first temperature and the threshold value, and a second gain value is calculated based on a difference between the power value at a second temperature which varies with the first temperature and the threshold value, and
when adjusting the output of the transmission signal, the threshold value is changed according to a comparative result of the first gain value and the second gain value.
