Abstract

A secondary-battery electrode manufacturing method that allows a secondary-battery electrode including a neat linear cut portion to be stably manufactured at a high speed is provided. A method of manufacturing a secondary-battery electrode (), which is an example of an embodiment, comprises a first step of forming an active material layer () on at least one surface of a long core body (). The method of manufacturing the secondary-battery electrode (), which is an example of the embodiment also comprises a second step of cutting an electrode precursor () into a predetermined shape by using a continuous wave laser, the electrode precursor () being the long core body () having the active material layer () formed thereon.
