JOINED BODY AND CERAMIC HEATER
To provide a technique capable of improving bondability between members that contain ceramic as main components.SOLUTION: There is provided a joined body in which a first ceramic member containing ceramic as main components and a second ceramic member containing ceramic as main components are joined. The joined body includes a junction which joins the first ceramic member and the second ceramic member and which contains, as main components, a composite oxide containing a rare earth element. The first ceramic member has a first joining surface joined to the second ceramic member through the junction. At least one of the first ceramic member and the second ceramic member contains a rare earth element. When A represents concentration of a rare earth element near a first surface in the first ceramic member, B represents concentration of a rare earth element near the first joining surface in the first ceramic member, and C represents concentration of a rare earth element in the second ceramic member, A>B and A>C are satisfied.SELECTED DRAWING: Figure 2
【課題】セラミックを主成分とする部材同士の接合性を向上させる技術を提供する。【解決手段】セラミックを主成分とする第１セラミック部材と、セラミックを主成分とする第２セラミック部材と、が接合された接合体であって、第１セラミック部材と第２セラミック部材とを接合する、希土類元素を含む複合酸化物を主成分とする接合部を備え、第１セラミック部材は、接合部を介して第２セラミック部材と接合される第１接合面を有し、第１セラミック部材、および第２セラミック部材の少なくともいずれか一方は、希土類元素を含有し、第１セラミック部材の第１面近傍の希土類元素の濃度をＡとし、第１セラミック部材の第１接合面近傍の希土類元素の濃度をＢとし、第２セラミック部材の希土類元素の濃度をＣとしたとき、Ａ＞Ｂ、かつＡ＞Ｃを満たす。【選択図】図２
