A vehicle-mounted sensor to be mounted on a vehicle includes: a light emission unit that emits infrared light of a first wavelength range and infrared light of a second wavelength range into space outside the vehicle, a water molecule having respective different light absorption factors to the infrared light of the first wavelength range and the infrared light of the second wavelength range; a light detection unit that detects the infrared light of the first wavelength range and the infrared light of the second wavelength range separately; and a water detection unit that detects water in the space outside the vehicle on the basis of a difference between a light amount of the infrared light of the first wavelength range and that of the infrared light of the second wavelength range detected by the light detection unit.
