A vehicle meter apparatus has a judging section that judges whether an automatic air conditioner purpose ambient temperature sensor is provided by comparing an input signal value inputted from an automatic air conditioner to an input section with a set threshold value and judges whether a display purpose ambient temperature sensor is provided by comparing the input signal value inputted from the display purpose ambient temperature sensor with the set threshold value when an internal power supply is supplied to input section and a display output section which displays an ambient temperature external to the vehicle on a second display section on a basis of a temperature detection signal from either of these sensors in a case where the judging section judges that the automatic air conditioner ambient temperature sensor is provided and in a case where the judging section judges that the display purpose ambient temperature is provided.
