Such SR heating element is to perform a temperature self-regulation function, so that the temperature is kept constant in the set temperature range while adjusting the heating state in response to the ambient temperature environment.

That is, the SR heating element continuously maintains the set temperature around the SR heating element. If the predetermined region temperature around the SR heating element becomes lower than the set temperature due to external influences, the SR heating element generates heat at a high temperature to generate heat around the SR heating element. The predetermined region temperature is quickly reached to the set temperature, and when the predetermined region temperature around the SR heating element becomes high, the predetermined region temperature around the SR heating element is lowered while operating.

In addition, the heat generating state of the SR heating element is controlled according to the difference between the predetermined region temperature and the set temperature around the SR heating element, the larger the difference between the predetermined region temperature and the set temperature around the SR heating element is to generate a high temperature so that the rapid rise in temperature Has performance.

The content of the (B) resistance component is preferably 46 to 62% by weight. When the content of the resistive component is less than 46% by weight, it is not preferable to insufficient heat generation performance of the heating element, and when it exceeds 62% by weight, it is not preferable because the stability of temperature control is lowered.

The content of the component for correcting this in the resistive component is preferably 1/10 to 1/100 at%. Calibration here can be understood as an additive which is added in order to further improve the effect of the resistive component.

It is preferable that the average particle diameter of a mixture is 0.5-5.0 micrometers in a resistance component.

The resistance component determines the base level of the relative resistance and the temperature resistance coefficient, and the calibration components of the molybdenum and boron additives change the relative resistance value. The change in the temperature resistance coefficient is controlled by changing the dispersion value of the particle component to 0.5-5 탆, which is determined by the preparation time in the ball mill. It is controlled by PSK-12, an instrument that measures relative surfaces by air permeation.
