Abstract
An electrode embedded ceramic structure includes: a first ceramic layer; an electrode layer formed on the first ceramic layer; and a second ceramic layer covering the first ceramic layer and the electrode layer, the second ceramic layer being thinner than the first ceramic layer. In a cross section of the first ceramic layer, the electrode layer, and the second ceramic layer along a laminating direction in this electrode embedded ceramic structure, T1 and T2 satisfy Equation (T2−T1)/T2≤0.15, where T1 denotes a least thickness in the second ceramic layer, and T2 denotes an average thickness of the second ceramic layer.
