Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a metal-ceramic bonded material having stable bonded state and high bonding strength and provide its production method. SOLUTION: A metallic part 3 and a ceramic part 2 are bonded together at their butt ends interposing a reaction layer 4 being in contact with the ceramic part 2 and a soldering material layer 5 being in contact with the metallic part 3. The ceramic part 2 is made of e.g. an alumina-based ceramic composed mainly of alumina and the metallic part 3 is made of a Ni-containing alloy such as an Fe-Ni-Co alloy The reaction layer 4 contains Ti as a main active metal element and the soldering material layer 5 contains a Ag-Cu alloy as a main component. A Ti-Ni intermetallic compound is scarcely formed between the soldering material layer 5 and the metallic part 3.
