である。DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to FIG. FIG. 1 shows an outline drawing of a high frequency induction coil. In FIG. 1, the high frequency induction coil has a nickel layer 2 of 100 to 5 on the surface of a core material 1 obtained by sintering silicon nitride into a coil shape.
The coating is formed to a thickness of 00 μm by an electrophoretic method.

イルはニッケル層２の融点に近い温度まで使用できる。The high frequency induction coil induction heats the load by applying electric power. At this time, the high frequency induction coil itself generates heat or receives radiant heat from the load. However, since the silicon nitride core material 1 has high heat resistance capable of being used up to about 1500 K, this high frequency induction coil can be used up to a temperature close to the melting point of the nickel layer 2.
