ABSTRACT:
A ceramic-metal composite assembly includes a ceramic member having a stab shaft and a metallic member having a recess. The ceramic member and the metallic member are joined together by press fit, i.e., by fitting the stab shaft into the recess. The stab shaft and the recess after extraction of the stab shaft from the recess has a set relationship of 50 .mu.m.ltoreq.X-Y.ltoreq.150 .mu.m where X is an outer diameter of the stab shaft and Y is an inner diameter of the recess whilst a surface roughness Rz of the recess in the circumferential direction thereof after extraction of the stab shaft from the recess is 1.5 .mu.m or less.
