A rain sensor including: a received light amount determination unit configured to output a detection result different in when a raindrop is adherent to a windshield glass of a vehicle and when no raindrop is adherent thereto; a temperature/humidity sensor configured to detect temperature and humidity in a vehicle cabin of the vehicle; a contactless temperature sensor configured to contactlessly detect temperature of the windshield glass; a fogging detection unit configured to detect that fogging has occurred or is likely to occur on a vehicle cabin inner side of the windshield glass on a basis of detection signals of the temperature/humidity sensor and the contactless temperature sensor; and a raindrop determination unit configured to determine whether or not a raindrop is adherent to the windshield glass on a basis of a detection result of the received light amount determination unit and a detection result of the fogging detection unit.
