Abstract: 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.

Abstract: A solid electrolyte assembly includes a substrate, a first electrode layer, and a solid electrolyte layer, wherein the first electrode layer and the solid electrolyte layer are stacked in this order on one face of the substrate. The first electrode layer includes: platinum or the like; and a metal oxide having ion conductivity. The substrate has a plurality of through-holes (hole portions) extending in a direction that intersects a face of the substrate that is opposed to the first electrode layer. The metal oxide preferably has oxide ion conductivity. The metal oxide preferably includes one or more rare earths.
