Patent number: 10639736Abstract: A ceramic-metal structure in which a metallic body (2) is inserted into or disposed above a through hole (4h) of a ceramic substrate (4) and which includes an annular pad layer (6) disposed around the through hole; an annular ring member (8) joined to the pad layer via a first brazing filler portion (10) and having a coefficient of thermal expansion smaller than that of the metallic body; a second brazing filler portion (12) intervening between the ring member and metallic body; and brazing filler flow prevention layers (7a, 7b) covering an outer surface of the pad layer so as to expose a central region (6c) of the outer surface of the pad layer facing the first brazing filler portion. The first brazing filler portion joins the central region and the ring member without projecting to a radially inner or outer side of the flow prevention layers.Type: GrantFiled: July 14, 2017Date of Patent: May 5, 2020Assignee: NGK SPARK PLUG CO., LTD.Inventors: Muneyuki Iwata, Yoshiaki Nagaya, Toshikazu Horio, Shigeyuki Yamamoto
