Abstract
A ceramic structure including a metallic body such as an electric heater. The metallic body is retained in a retaining portion of the ceramic structure in such a manner that a minute cavity is provided around the metallic body. This ceramic structure is produced by forming an organic film around the metallic body, preparing a ceramic structure including the metallic body surrounded with the organic film in a retaining portion of the ceramic structure, and heating the resultant structure so as to decompose the organic film, whereby a minute cavity is formed around the metallic body.
