To provide an electrode plate capable of achieving a large capacity of a battery without causing cracks or chipping even when an electrode material is thickly coated on a sheet-like current collector. An electrode plate 100a constituting a positive electrode or a negative electrode of a battery having a flat plate shape and a sheet-like electrode material 103a containing an electrode active material, a conductive additive, a binder, and a thickener, made of a metal foil. The electrode plate is coated on the current collector 102, and the thickener is an alginate. [Selection] Figure 2 |
