The laminate includes first conductor layers, second conductor layers, dielectric layers and insulating layers laminated in the z direction. Each first conductor layer is connected to the first side covering portion and spaced apart from the second side covering portion. Each second conductor layer is connected to the second side covering portion and spaced apart from the first side covering portion. The insulating layers have a lower dielectric strength than the dielectric layers. Each dielectric layer is sandwiched between a first conductor layer and a second conductor layer. The insulating layers include one sandwiched between two first conductor layers and one sandwiched between two second conductor layers.

摘要： A layered body includes: a substrate; and an oxide portion positioned on the substrate. An oxide that constitutes the oxide portion contains at least two or more rare-earth elements: silicon; and oxygen. The oxide that is contained in the oxide portion exhibits a diffraction peak derived from a (004) plane at a position of 2θ=51.9°±0.9° in an X-ray diffraction pattern, and has an apatite crystal structure. The ratio of linear expansion coefficient of the oxide that constitutes the oxide portion in an a-axis direction relative to linear expansion coefficient of the substrate is 0.15 or more and 1.45 or less.
