PROBLEM TO BE SOLVED: To simultaneously secure both the reliability of a joint state between an insulator and a conductive pin and the safety of a living body. SOLUTION: The joint body of ceramics and metal is configured such that a ceramic body and a metallic body are joined via a first joint layer containing, as a main component, at least one kind selected from a first group consisting of Pt and Pd, and a second joint layer containing Au, as the main component, and containing, as a sub-component, at least one kind selected from the first group. The first joint layer contains a segregation phase containing, as the main component, at least one kind selected from a second group consisting of Ir, Ru, and Rh. COPYRIGHT: (C)2011,JPO&INPIT
