<p>PROBLEM TO BE SOLVED: To provide a wiring pattern for a heater wire which is suitable for a plane heater such as an electric blanket and an electric carpet, and can sufficiently reduce leakage of magnetic field. SOLUTION: In this wiring pattern 100, a lead wire 20 provided with insulating coating 12 around a conductor 11 is wired in parallel to a heater wire 10 in which a heating strand 2 is spirally wound around a core string 1, a fusing layer 3 is provided around it, a signal wire 4 is spirally wound around the fusing layer and a protective coating layer 5 provided around the signal wire, and a mutually reverse current can be sent to the heater wire 10 and the lead wire 20.</p> |
