Abstract
A metal-ceramic joined body is provided in which the surface roughness of the metal is low, and the joined body is unlikely to break. Provided is a metal-ceramic joined body including a metal mainly composed of titanium and a ceramic, in which, regarding the X-ray diffraction peak intensity of a surface portion of the metal excluding a joining region to the ceramic, at least one of I110 and I012 is larger than I011, where I011 is the intensity of a peak attributable to a first plane of hexagonal α titanium, I110 is the intensity of a peak attributable to a second plane of hexagonal α titanium, and I012 is the intensity of a peak attributable to a third plane of hexagonal α titanium.
