All-solid state secondary cell and production method for same

An all-solid state secondary cell comprising

• a positive electrode collector,
• a negative electrode collector, and
• a powder laminate disposed between the positive electrode collector and the negative electrode collector,
• wherein the powder laminate has a positive electrode powder layer, a negative powder layer, a solid electrolyte layer disposed between the positive electrode powder layer and the negative electrode powder layer, and an absorption layer covering an outer periphery of the positive electrode powder layer or the negative electrode powder layer, the absorption layer including at least one selected from the group consisting of a hydrogen sulfide adsorption layer and a moisture adsorption layer;
• wherein the powder laminate comprises a peripheral edge part and a center part surrounded by the peripheral edge part;
• and
• wherein a thickness of the peripheral edge part of the powder laminate is greater than a thickness of the center part of the powder laminate.
