PURPOSE: To provide a manufacturing method of an electrode plate for battery that can increase the binding capacity of a binder without heating in high temperature and without increasing the mixture ratio in the mixture, while using a binder of polyolefin system resin such as PE which is relatively cheep cost and stable material for a battery. CONSTITUTION: A mixed compound of polyolefin system resin used for a binder 11 and a solvent 13 is heated at a temperature in which a part of or whole polyolefin resin can be melted, and an adhesive solution 17 which is made a gel of high viscosity as a whole is made. A mixture of the adhesive solution 17, an active material and a conductive material are kneaded and made a gel mixture 19, and the gel mixture 19 is applied on a current collector and form a mixture layer 20. The current collector 8 formed with the mixture layer 20 is heated and after drying molded by pressing to a prescribed thickness. |
