Abstract

An electrode sheet manufacturing device includes a conveyance device, a first press device, a second press device, and a stepped roll pressing device. The first press device is a device that roll-presses a non-formed portion of an electrode sheet by a pair of rubber rolls. At least one of the pair of rubber rolls includes a shaft and an elastic body. A diameter of the shaft in a portion thereof that presses a boundary portion between the non-formed portion and the electrode active material layer is larger than a diameter of the shaft in a portion thereof that presses a more outer side than the boundary portion. A thickness of the elastic body in the portion thereof that presses the boundary portion is smaller than a thickness of the elastic body in the portion thereof that presses the more outer side than the boundary portion.
