Abstract: An interconnect structure includes: an interconnect layer containing a metal element as a main component and extending in a direction; a metal layer opposite to the interconnect layer, and a solid electrolyte layer between the interconnect layer and the metal layer. The solid electrolyte layer encloses the interconnect layer at least in a cross-sectional view taken along a plane orthogonal to the direction. The interconnect layer and the metal layer are electrically insulated from each other by the solid electrolyte layer.

Abstract: Provided is a cathode active material including a lithium composite oxide and a covering material which covers a surface of the lithium composite oxide. The lithium composite oxide is a multi-phase mixture including a first phase having a crystal structure which belongs to a space group C2/m and a second phase having a crystal structure which belongs to a space group R-3m. The lithium composite oxide has an integral intensity ratio I(18°-20°)/I(43°-46°) of not less than 0.05 and not more than 1.15, where the integral intensity ratio I(18°-20°)/I(43°-46°) is a ratio of an integral intensity I(18°-20°) to an integral intensity I(43°-46°). The integral intensity I(α°-β°) is an integral intensity of a first peak which is a maximum peak present within a range of a diffraction angle 2θ of not less than α° and not more than β° in an X-ray diffraction pattern of the lithium composite oxide. The covering material has an electronic conductivity of not more than 106 S/m.
