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.
