To lengthen a travelable distance of a vehicle and a charging cycle, by reducing power consumption for heating the vehicle.
The heating device includes: a housing including a hollow through which ventilation air flows in a ventilation passage, the house being made of a metal material capable of shielding electromagnetic of micro wave, where the ventilation air flows into an opening at an upstream side and flows out of an opening at a downstream side, in a ventilation direction; a support body with a micro wave absorption element including a hollow with both ends opened to the upper stream side and the downstream side in the ventilation direction; a micro wave output means for outputting micro wave toward each micro wave absorption heating body, at a ventilation upstream side of the micro wave absorption heating body in the housing. When ventilation air passes from the upstream side to downstream side in the ventilation direction through the hollow of the micro wave absorption heating body, the ventilation air is heated by heating associated with absorption of the micro wave oscillated from the micro wave absorption heating body.
