An electrode sheet producing method by cutting out an electrode sheet with a laser beam (L1, L2) from an original sheet including an electrode portion obtained by applying an active material layer to at least one surface of a long metal foil and an ear portion that is at least one side portion of the metal foil on which the active material layer is not applied, the electrode sheet producing method comprising: continuously moving the original sheet ; separating the ear portion from the electrode portion with a first laser beam (L1) in an ear portion separating region provided in a middle of movement of the original sheet , being characterised by : taking up the separated ear portion at a position where the ear portion is separated, in a direction separated from a running direction of the electrode portion , by forming a separation angle (α) between the electrode portion and the ear portion at an irradiation point (Pm) of the laser beam (L1), thereby separating the ear portion from the electrode portion when melting occurs at the irradiation point (Pm) of the laser beam (L1), and moving the laser beam (L1) in the ear portion separating step to cut out a tab connected to the electrode portion , from the ear portion ; thereafter moving a second laser beam (L2) from one edge of the electrode portion to another edge of the electrode portion in synchronization with a moving speed of the electrode portion in a cutting region provided downstream of the ear portion separating region, while applying tension (T) in the running direction of the electrode portion to a cut portion of the electrode portion , to cut the electrode portion at a predetermined interval to continuously form the electrode sheet with the tab ; and thereafter collecting the electrode sheet with the tab and the separated ear portion . continuously moving the original sheet ; separating the ear portion from the electrode portion with a first laser beam (L1) in an ear portion separating region provided in a middle of movement of the original sheet , taking up the separated ear portion at a position where the ear portion is separated, in a direction separated from a running direction of the electrode portion , by forming a separation angle (α) between the electrode portion and the ear portion at an irradiation point (Pm) of the laser beam (L1), thereby separating the ear portion from the electrode portion when melting occurs at the irradiation point (Pm) of the laser beam (L1), and moving the laser beam (L1) in the ear portion separating step to cut out a tab connected to the electrode portion , from the ear portion ; thereafter moving a second laser beam (L2) from one edge of the electrode portion to another edge of the electrode portion in synchronization with a moving speed of the electrode portion in a cutting region provided downstream of the ear portion separating region, while applying tension (T) in the running direction of the electrode portion to a cut portion of the electrode portion , to cut the electrode portion at a predetermined interval to continuously form the electrode sheet with the tab ; and thereafter collecting the electrode sheet with the tab and the separated ear portion . thereafter moving a second laser beam (L2) from one edge of the electrode portion to another edge of the electrode portion in synchronization with a moving speed of the electrode portion in a cutting region provided downstream of the ear portion separating region, while applying tension (T) in the running direction of the electrode portion to a cut portion of the electrode portion , to cut the electrode portion at a predetermined interval to continuously form the electrode sheet with the tab ; and thereafter collecting the electrode sheet with the tab and the separated ear portion . <EOS>
