Abstract
An electrode structure includes a positive electrode layer and a positive electrode collector member. The positive electrode collector member includes a positive electrode collector foil, a carbon film, and a hot melt adhesive agent. A positive electrode total specific surface area is more than or equal to 2.2 m/g and less than or equal to 3.0 m/g, the positive electrode total specific surface area being represented by a total of a product of weight ratio and specific surface area of a positive electrode active material, a product of weight ratio and specific surface area of a solid electrolyte, and a product of weight ratio and specific surface area of a conductive material. A softening point of the hot melt adhesive agent is more than or equal to 100° C. and less than or equal to 130° C.
