SOLID ELECTROLYTE CELL AND PRODUCTION METHOD THEREOF

摘要

A solid electrolyte cell is formed by a concave formation step for forming a concave portion (10) having a predetermined depth at a predetermined position of a substrate (a1) and a layering step for arranging a power generation element (f) in the concave portion (10). This significantly suppresses a height protruding from the substrate surface and improves the step coverage of an upper layer, thereby producing a solid electrolyte secondary cell having an excellent reliability.
