Abstract

An object is to provide an electrode assembly in which the adhesiveness of a mixture agent layer onto a current collector can be accurately improved, and an electric storage device including the electrode assembly. Provided are an electrode assembly including a sheet-shaped current collector that has, on at least one face thereof, a mixture agent layer containing an active material and is spirally wound, in which the current collector has, in a portion on a side of at least one end of a winding axis, a non-mixture agent layer part having no mixture agent layer formed therein, and a mass per unit area of the mixture agent layer is larger in an edge portion on the side of the non-mixture agent layer part by 0.3% or more and 1.0% or less than in a portion other than the edge portion; and an electric storage device including the electrode assembly.
