    Abstract: Provided is a degassing method for an electrode paste that introduces the electrode paste formed by kneading a solid content containing an electrode active material and a dispersion medium into a decompressed container and degassing the electrode paste while a shear force is applied to the electrode paste. A ratio of the solid content in the electrode paste is set to be 55 mass % or more, and a pressure in the decompressed container is set to be ?50 kPa or more. It is possible to suppress both remaining bubbles and dry of the electrode paste, thus enhancing a product yield.
