Claims (1)

[Scope of utility model registration request] an outside air temperature detection means that is disposed at a position susceptible to the heat radiation of an engine mounted on a vehicle and that detects the temperature of outside air and outputs an outside air temperature detection signal; and an outside air temperature detection means that detects the temperature of a cooling water of the engine and outputs a cooling water temperature detection signal. cooling water temperature detection means for outputting the temperature of the outside air and the temperature of the cooling water based on the outside temperature detection signal and the cooling water temperature detection signal; a storage means for storing the temperature of the outside air according to the outside air temperature detection signal, and a temperature difference based on the difference between the outside air temperature detection signal and the cooling water temperature detection signal when the ignition switch is turned on, which is compared with a preset temperature. A vehicle outside temperature display device comprising a comparison means and a control means for displaying the outside air temperature stored in the storage means as the outside air temperature when the temperature difference is larger than the set temperature.
