Abstract
An electric storage device includes an electrolyte and an electric storage unit including a positive electrode including a positive-electrode collector electrode and a positive-electrode active-material layer disposed on the positive-electrode collector electrode; a negative electrode including a negative-electrode collector electrode and a negative-electrode active-material layer disposed on the negative-electrode collector electrode and facing the positive-electrode active-material layer; a first insulating layer bonded to the positive electrode and the negative electrode to isolate the positive electrode and the negative electrode from each other; and a region that is sealed with the first insulating layer in plan view and that holds the electrolyte between the positive electrode and the negative electrode, wherein an air permeability P of the first insulating layer satisfies the formula 1250 s/100 cc<P<95000 s/100 cc.
