To provide a ceramic structure that can prevent cracks from generating in a ceramic base material and a conductive member even if using a long term.SOLUTION: A ceramic structure 1 comprises: a ceramic base material 10 having a principal surface 11, a hole 12 extending from the principal surface 11 to an inside of the ceramic base material 10; a metal electrode layer 20 embedded in the ceramic base material 10; and a conductive member 30 that is electrically connected to the metal electrode layer 20, and is embedded in the ceramic base material 10 so as to configure a bottom 13 of the hole 12. The ceramic structure 1 further comprises: a first metallic member 40 that is bonded to the conductive member 30 by a solder material 21, and has a mean coefficient of linear expansion greater than a mean coefficient of linear expansion of the conductive member 30; one or more second metallic members 50 that have mean coefficients of linear expansion greater than that of the first metallic member 40; and a metallic terminal 60 that is bonded to the second metallic member 50, and has a mean coefficient of linear expansion greater than the second metallic member 50.SELECTED DRAWING: Figure 2
