Abstract of the Disclosure Disclosed herein is a metal-ceramic composite article comprising a metallic member made of a precipita- tion hardening alloy and a ceramic member, wherein a projection formed at the ceramic member is fitted into a hole or a through hole formed at the metallic member and the metallic member of the composite article is hardened through precipitation hardening. A process for manufacturing such a metal-ceramics composite article is also disclosed. The manufacturing process comprises steps of: fitting a projection formed at a ceramic member into a hole formed at a metallic member made of a precipitation hardening alloy in a state in which precipitation-hardening is not carried out to form a metal-ceramics joint body, and subjecting the thus formed metal-cramics composite body to a precipitation hardening treatment to harden the metallic member.
