Abstract
There is provided a method for producing an electrode body including a current collection foil, an electrode mixture layer, a heat resistant layer, and a separator layer are laminated in this order. The method includes applying a liquid heat resistant material forming the heat resistant layer to the electrode mixture layer on an electrode plate that is obtained by forming an electrode mixture layer on the current collection foil and disposing the porous separator layer on the liquid heat resistant material before the liquid heat resistant material according to the application is dried after applying the liquid heat resistant material.
