The present invention provides an all-solid state secondary cell equipped with: a positive electrode collector; a negative electrode collector; and a powder laminate placed between the positive electrode collector and the negative electrode collector. The powder laminate has: a positive electrode powder layer; a negative electrode powder layer; and solid electrolyte layers that are placed between the positive electrode powder layer and the negative electrode powder layer, and also cover the outer periphery of the positive electrode powder layer and the negative electrode powder layer. The powder laminate comprises a peripheral edge part, and a center part surrounded by this peripheral edge part. The thickness of the peripheral edge part is the thickness of the center part or greater.
