A vehicle includes an internal combustion engine, an electrically-heated catalyst device provided in an exhaust passage thereof, and an electronic control unit configured to control base material electric power supply supplied to a conductive base material. The catalyst device includes the conductive base material that generates heat upon energization, and a catalyst heated through the conductive base material. The electronic control unit determines whether the conductive base material is in a stagnant period, where temperature of the conductive base material partially stagnates in a prescribed temperature zone, the stagnant period occurring when water is present inside the catalyst device in a process of increase in temperature of the conductive base material. When determining that the conductive base material is in the stagnant period, the electronic control unit controls the base material electric power supply to be lower than when determining otherwise.
