To provide a temperature estimation device capable of estimating each temperature of a plurality of measuring object positions in the device more accurately, while suppressing cost.

A temperature measuring part 130 measures the temperature of a control part 300. A temperature table holding part 110 holds correlatively the installation state of a base station 100, the temperature of the control part 300, and estimated temperatures of wireless parts 400a, 400b. A temperature estimation part 140 estimates the estimated temperatures of wireless parts 400a, 400b correlated with the temperature measured by the temperature measuring part 130 and the installation state of the base station 100, as the temperatures of wireless parts 400a, 400b on reference to the temperature table holding part 110.
