PROBLEM TO BE SOLVED: To provide a heat medium heating device that can simplify electric wires and terminals and that is made compact and light in weight. SOLUTION: The heat medium heating device 21 includes a plurality of electric heaters 21a, 21b, 21c, 21d each having an exit temperature sensor measuring a temperature of water flowing out from the device and an entrance temperature sensor measuring a temperature of water flowing into the device. All exit temperature sensors are connected to electric wires 32a, 32b, 32c, 32d that transmit measured values, and only one of the entrance temperature sensors is connected to an electric wire 33 that transits a measured value.
