Abstract
A metal-ceramic composite body is disclosed, which comprises a metallic member having a depression or through-hole therein, and a ceramic member having a protrusion capable of inserting into the depression or through-hole. Both the members are joined to each other through interference fitting below such a temperature that the structure of the metallic material begins to change into austenite phase or a temperature between the above temperature and a service temperature.
