PROBLEM TO BE SOLVED: To provide a method for manufacturing an electrode for a secondary battery, which prevents a segregation of a binder in an electrode mixture layer and thereby can enhance adhesion between an electrode collector and the electrode mixture layer.SOLUTION: The method for manufacturing the electrode comprises: applying a first pasty composition containing at least an electrode active material and a first binder having at least one hydrophilic group, on a surface of an electrode collector (S10); applying a second pasty composition containing at least an electrode active material and a second binder having at least one hydrophilic group, on the first composition (S20); and drying the first composition and the second composition to form an electrode mixture layer (S30). The number of moles of the hydrophilic group per unit mass contained in the first binder is less than the number of moles of the hydrophilic group per unit mass contained in the second binder. |
