The invention provides an electric storage device which restrains resistance increase caused by insufficient electrolyte feeding. The electric storage device includes: a rolled electrode assembly 10 formed by winding a positive electrode, a negative electrode, and a separator so as to have curved portions and linear portions; current collectors 7; and an electrolyte solution 3. A positive electrode substrate has at one end 10A an unformed portion 11E formed without a positive electrode mixture layer, and a negative electrode substrate has at the other end 10B an unformed portion 13E formed without a negative electrode mixture layer. The current collectors 7 are connected respectively to at least part of the linear portions in the unformed portion of the positive electrode at the one end 10A and that of the negative electrode at the other end 10B. The one end 10A in the positive electrode has a length greater than the winding length, and/or the other end 10B in the negative electrode has such a length.
