Abstract
A ceramic-metal composite body comprises a ceramic member with a projection formed thereon and a metallic member with a depression or through hole formed therein. The ceramic member and the metallic member are bonded together by fitting the projection of the ceramic member into the depression or through hole of the metallic member. The difference between the outer diameter of the projection of the ceramic member and the inner diameter of the depression or through hole of the metallic member when the projection of the ceramic member is extracted from the depression or through hole of the metallic member is not less than 0.2% of the outer diameter of the projection of the ceramic member.
