PLANE HEATING ELEMENT WITH DETECTION WIRE

PROBLEM TO BE SOLVED: To provide a plane heating element with a crew-detecting detection wire capable of precise detection. SOLUTION: Since a heater wire and a detection wire are arranged on the same plane of a base material, it is easier to place both the wires at a constant positional relation, and at that, there is no risk of the detection wire arranged in crossing or adjacent to the heater wire due to shift at or after its mounting on the seat, and an adverse effect on detection characteristics the heater wire might give on the detection wire is made constant, so that an effect enabling precise detection is obtained.
