There are provided method and apparatus for manufacturing a polarizable electrode for electric double layer capacitor is provided which is capable of preventing porosities, cracks, or breakage of a sheet as much as possible when molding materials are formed into a sheet form and improving the yield of the molding materials. The manufacturing apparatus is used before granulated molding materials that are finely divided and crushed are moved to a calendar molding machine. The apparatus includes a mixing machine, a vibrating sieve, and a vibrating feeder. In the mixing machine, when the granulated molding materials are mixed with IPA as a binding assistant in a hermetically sealed mixing container, they are agitated by agitating blades. With this, even when during the mixing, the granulated molding materials adhere with each other to form lumps, the lumps are crushed by the agitation of the agitating bladesso that the molding materials are disintegrated into smaller particles. The molding materials mixed with IPA are sieved by the vibrating sieveand conveyed to the calendar molding machinealong a conveyance pathof the vibrating feeder, whereby the molding materials are formed into a sheet form.
