い。2. Description of the Related Art Generally, when two solids having a temperature difference are brought into contact with each other, heat is conducted from a high-temperature solid to a low-temperature solid.
As shown in FIG. 5, the surfaces of the solids 11 and 12 hardly coincide with each other, even if the surfaces are almost mirror-finished, and the contact surfaces 13 and 14 have irregular shapes, respectively. A gap 15 is formed between the contact surfaces 13 and 14. A gas such as air is interposed in the gap 15, and the gas has a lower heat conduction than a solid, so that when the heat is conducted, the gas becomes a resistance. Therefore, in the case of FIG.
Mainly, from the high temperature solid 11 to the low temperature solid 12 through a contact point or a contact line which is a contact portion 16 of the two solids 11 and 12.
As heat flows, the heat conductivity is low and the heat resistance is high.

The thermal compound 17 is applied to the contact surfaces 13 and 14 of the two solids, and the gap 15 formed in the contact surfaces 13 and 14 of the two solids 11 and 12 is eliminated. However, the heat resistant temperature of the thermal compound 17 is as low as about 100 ° C.
There was no use for a high temperature of about 000 ° C., and at a higher temperature, contact thermal resistance could not be reduced. Further, it is very difficult to apply the thermal compound 17 uniformly to the contact surfaces 13 and 14, and it is difficult to reproduce the contact thermal resistance uniformly.
