ABSTRACT:
Disclosed herein is a metal-ceramic composite body having a ceramic member with a small diameter portion and a large diameter portion which are formed by providing a ceramic member with a projection and a metallic member with a recessed portion or through hole. The ceramic member and the metallic member are bonded together by inserting the small diameter portion into the recessed portion or through hole such that a space being not less than the diameter of the small diameter portion is provided between the edge surface of the metallic member on the side of the ceramic member at the bonding portion and the back surface of the large diameter portion of the ceramic member. The thickness of the edge portion of the metallic member is gradually reduced toward the ceramic member at a radius of curvature of not smaller than 0.4 times as large as the diameter of the small diameter portion. A method of producing the metal-ceramic composite body is also disclosed herein.
