An object of the present invention is to provide a manufacturing method capable of winding an electrode with a small radius of curvature when producing a wound type electrode used in a secondary battery, a capacitor, or the like. A slurry containing an active material in a three-dimensional network aluminum porous body having a thickness of 1.0 to 5.0 mm, a porosity of 80 to 98%, an aluminum basis weight of 90 to 450 g / m 2 , and a pore diameter of 50 to 1000 μm. And drying, and then adjusting the thickness to 0.1 to 0.9 mm, and filling the active material to 40 to 65%. [Selection figure] None |
