    • The invention provides a multilayer secondary battery in which a positive electrode having a positive electrode active substance layer formed on a flat sheet-form collector and a negative electrode having a negative electrode active substance layer formed on a flat sheet-form collector are stacked together in opposite relation via a separator. The positive electrode active substance layer differs in area from the negative electrode active substance layer. Active substance-free portions with no active substance layer coated on them are formed on at least adjoining two sides of the outer periphery of a collector of a smaller area electrode having a smaller active substance layer area. The surface of the collectors at the active substance-free portions is covered with an insulating substance layer. The end face of the insulating substance layer that faces away from a side contiguous to an active substance layer and the end face of a larger area electrode having a larger active substance layer area are located and stacked together on the same plane that intersects vertically an electrode plane.
