Description of the Related Art Generally, as a thermosensitive electric wire whose capacitance changes with temperature, there is a thermosensitive electric wire as shown in FIG. 2, which uses a polymer thermosensitive material 4 made of a polyamide composition. If one of the pair of electrodes 2.3 is also used as a heating wire, it becomes a heat-sensitive heater wire and is used as a heater wire for an electric blanket. As shown in FIG. 3, the temperature control device for this heat-sensitive wire includes a heat-sensitive heater wire 6, a temperature setting (variable) resistor 7. The volume resistor 8 was connected in series. In FIG. 3, a neon lamp 9 detects a change in the impedance of a thermosensitive heater wire 6, and a power control element (thyristor) 1o is controlled based on the signal.

Problems to be Solved by the Invention However, when the polymer temperature sensitive body is of a type whose capacitance C changes depending on the temperature, its impedance value is a capacitive reactance of 1/2πfO depending on the frequency f of the AC power supply. To show, due to the difference between commercial frequencies 50Hz and 60Hz,

EXAMPLE Hereinafter, an example of the present invention will be described with reference to the drawings. A parallel circuit consisting of a temperature setting variable resistor 7 and a capacitor 11 is used by connecting it in series with a thermosensitive electric wire 6 as shown in FIG. If the parallel resistance (R1) 12 of the thermal heater wire is further added to this, the temperature fluctuation will be further reduced. In this case, each constant is 1/ωCx2Rvy+τ, Rx':2
It is desirable to set it to Z (1o'C).

That is, as shown in FIG.
.. The pressure is divided by a volume 8 and a temperature setting circuit (parallel connection of 7 and 11) including a capacitance component. This circuit is not a series circuit of an electric capacitor (thermal heater wire) and a resistor (temperature setting resistor) as in the past, but a series circuit of an electric capacitive electric wire and a temperature setting circuit including an electric capacitance component, so that the frequency Dependency can be greatly reduced. As shown above, when 1/ωOX < RVRT, the effect is large, but when variable by RVltT, the range becomes small, so it is desirable that 1/ωCx = RvRτ. On the other hand, the parallel resistance R, of the thermal heater is R1〉Z (10°C
), it is possible to reduce the frequency dependence without significantly reducing the temperature sensitivity of the thermosensitive heater wire.
