Abstract
A heat medium heating device including flat heat exchange tubes and PTC heaters stacked in a plurality of layers, the heat medium heating device being capable of correctly and accurately detecting the temperature of a circulating heat medium; and a vehicular air-conditioning device including the same. In a heat medium heating device, flat heat exchange tubes each including an inlet header part and an outlet header part and PTC heaters are stacked in a plurality of layers, and are incorporated in a casing including a heat medium inlet path and a heat medium outlet path communicated with the inlet and outlet header parts. In the heat medium heating device thus configured, an inlet temperature sensor and an outlet temperature sensor that detect the temperature of a heat medium are provided around the inlet and outlet header parts of the lowermost flat heat exchange tube in the stacked structure.
