There is provided a heat flux sensor 10 with first and second interlayer connection members 130, 140 composed of different metals from each other of which metal atoms maintain a predetermined crystal structure embedded in first and second via holes 101, 102 of a thermoplastic resin made insulating substrate 100, the first and the second interlayer connection members are connected in series alternately, and a control unit 20 that performs abnormality determination of a heating element 30 disposed in a vehicle. The heat flux sensor 10 is provided to the heating element 30 and outputs a sensor signal corresponding to heat flux between the heating element 30 and an outside air, and the control unit 20 determines based on the sensor signal that there is abnormality in the heating element 30 when the heat flux between the heating element 30 and the outside air is out of a predetermined range. |
