Abstract

A method for producing an electrode sheet includes a first feeding process, a roll press process, and a second feeding process, which are performed in this order. At least one of a first tension per unit area obtained by dividing a tension applied to the electrode sheet in a longitudinal direction in the first feeding process by a cross-sectional area of the electrode sheet being fed in the first feeding process and a second tension per unit area obtained by dividing a tension applied to the electrode sheet in a longitudinal direction in the second feeding process by a cross-sectional area of the electrode sheet being fed in the second feeding process is 5.0 MPa or less.
