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 are a power generation element, an encoder, and a method of manufacturing a magnetic member capable of increasing generated power. Power generation element includes magnetic member that produces a large Barkhausen effect, coil wound around magnetic member, and ferrite member provided at an end of magnetic member to be aligned with coil along a winding axis direction of coil.
