Abstract
Provided is an all-solid-state sodium ion secondary battery in which a current collector is difficult to peel from an electrode layer and which can suppress the decreases in discharge capacity and discharge voltage. An all-solid-state sodium ion secondary batteryaccording to the present invention includes: a solid electrolyte layermade of a sodium ion-conductive oxide; a positive electrode layerformed on a first principal surfaceof the solid electrolyte layer; a negative electrode layerformed on a second principal surfaceof the solid electrolyte layer; and a current collector layerformed on a principal surface of at least one of the positive electrode layerand the negative electrode layer, wherein the current collector layeris made of at least one metallic material selected from the group consisting of aluminum, titanium, silver, copper, stainless steel, and alloys thereof, and the current collector layerhas a thickness of not less than 10 nm and not more than 10 μm.
