An exterior package for an electrode assembly of an electrochemical device includes a plurality of linear patterns. Each of the linear patterns has a cross-section of an uneven structure in a thickness direction of the electrode assembly and a linear pattern of the linear patterns includes a first element line and a second element line, which extend in different directions on a plane perpendicular to the thickness direction of the electrode assembly.

An electrode assembly includes an electrode stack structure including a first electrode assembly sheet having flexibility and a second electrode assembly sheet having flexibility, where and the first and second electrode assemblies are alternately disposed one on another, and a binding unit which binds a portion of the electrode stack structure. The first electrode assembly sheet includes first and second separator films disposed to face each other, a first electrode sheet which is disposed between the first and second separator films and includes a first electrode collector and a first active material layer, and a first confining unit which restricts a movement of the first electrode sheet with respect to the first and second separator films.
