Abstract: One object is to provide an electric storage element for electrochemical devices that can prevent fall of active material powder from an outer edge of an active material layer, thereby preventing functional disorders due to the fall of the active material powder. In accordance with one aspect, an electric storage element has laminated structure wherein active material layers (first active material layer and second active material layer) are placed between an ion permeable layer and a first collector layer and between the ion permeable layer and a second collector layer. The active material layers have a smaller outline than the ion permeable layer and are tightly enclosed with insulating layers (first insulating layer and second insulating layer) filling the respective ambient regions corresponding to the difference in outlines from the ion permeable layer.
