Abstract

A method for manufacturing an electrode for a secondary battery includes: applying a first layer slurry containing a first binder to a surface of a current collector, applying a second layer slurry containing a second binder on the first layer slurry before the first layer slurry is dried, and drying the first layer slurry and the second layer slurry after applying the first layer slurry and the second layer slurry to obtain a laminated structure in which a first layer and a second layer are laminated in this order on the current collector. The second layer slurry has a solid content ratio of more than 50% by mass and a composition ratio of the second binder of more than 2% by mass.
