PROBLEM TO BE SOLVED: To provide an electrode sheet which is strong in peel strength of an electrode active material layer and small in electrical resistance.SOLUTION: An electrode sheet 100 proposed herein includes: a band-like current collector foil 101; an undercoat 102 coated on the band-like current collector foil 101; and an electrode active material layer 103 formed on the undercoat 102 coated on the band-like current collector foil 101. Here, the undercoat 102 is made of resin having an adhesive force. Moreover, the undercoat 102 is coated in a vertical stripe pattern or an oblique stripe pattern along the longitudinal direction at intervals in the width direction of the band-like current collector foil 101. |
