PURPOSE:To uniformly fill an active mass by filling the active mass as vibration is applied in pores of a substrate comprising a foam-shape metal porous body having three dimensional continuous pore and pressing it. CONSTITUTION:A substrate 1 comprising a foam-shape nickel porous body is passed in a filling vessel 2 in which an active mass powder 3 comprising nickel hydroxide powder and metal nickel powder is filled, and at the same time vibration having 100Hz frequency, and 1.0mm. vibration width is applied with an oscillator 4. After a resin sheet 9 is placed on the under surface of the substrate 1, a resin solution 6 is sprayed. The substrate 1 is passed in a dryer 7, and the resin sheet 9 is placed on the surface of the substrate 1, then pressed to a prescribed thickness with a pair of rollers 10, and the sheet 9 and 9' and removed to obtain a finished electrode plate. Since the active mass powder is filled with vibration applied, uniform filling and uniform density of the active mass after press are achieved. |
