A charging device for a vehicle includes a connector configured such that a coupler for transmitting electric power from an external power supply to the vehicle is connectable to the connector, a charging circuit for transmitting electric power from the connector to a power storage device, a charging control unit for charging the power storage device by controlling the charging circuit while in an operating state, and for halting control of the charging circuit while in a halting state, and an activation control unit for keeping the charging control unit in the halting state until detecting that the connector receives electric power, in a case where connection of the coupler and the connector is detected, and for switching the charging control unit from the halting state to the operating state when it is detected that the connector receives electric power.
