<p>PROBLEM TO BE SOLVED: To join two components more simply and reliably.SOLUTION: A joined body 20 includes: a first component 22; a second component 24; and a joint part 30 that joins the first component 22 and the second component 24, the joint part 30 including an oxide ceramic including at least one transition metal, and composite particles 31 having higher Yang's modulus and lower thermal expansion coefficient compared to the oxide ceramic being dispersed in the oxide ceramic. The joined body 20 is manufactured in a joining process of making a laminate where a metallic raw material mixed with the transition metal powder and the composite particle 31 is disposed between the first component 22 and the second component 24, and forming the joint part 30 of the oxide ceramic by burning the laminate in an oxidative atmosphere (atmosphere) within a lower temperature range than the fusion point of the transition metal oxide. In the joining process, the laminate may be burnt between 400°C or higher and 900°C or lower. The composite particle 31 is preferably at least either one of SiC or AlO.</p> |
