Abstract
Heater electrodes and a sensor electrode both in a film shape are formed on the top surface of an insulation sheet without overlapping with each other. As a result, a seat heater has a small overall thickness. Then, the seat heater can be placed near the seating surface of a seat without making the seat less comfortable to sit in. The occupant is detected based on the impedance between the sensor electrode and the vehicle. As a result, it is possible to warm the occupant seated on the seat efficiently and detect the occupant with accuracy.
