FIG. 6 is one cross sectional view illustrating a cross section of an electrode, and is a drawing illustrating an example in which an active material film 300 containing an electrode active material 210 and conductive particles 220 is adhered to each of the two opposing surfaces of a current collector 500. The active material film 300 in FIG. 6 is an example illustrating a cut film sliced from the molded body in which the particulate electrode active material capable of plastic deformation is plastically deformed in the form of particles pressed by press molding to form an orientation of the electrode active material particles, or the electrode active material in the form of flakes is press-molded and packed in one direction to form an orientation (particle unit orientation) of the electrode active material particles. In addition, the active material film 300 in FIG. 6 is an example in which the active material bulk is sliced to form a cut surface vertically to an oriented direction of the electrode active material in the active material bulk, so that the thickness direction of the active material film and oriented direction (oriented direction of the active material particle unit) of the active material in the film are substantially in parallel to each other.
