PURPOSE: A method of manufacturing battery electrode substrate and battery electrode substrate is provided to have more retention power to the radiation material and to increase ointment quantity to the thickness direction. CONSTITUTION: Pressing with an embossing process to a thin metal sheet, concave portion is prepared to the entire sheet. In this concave portion process, a hole is made at each apex of a concave portion simultaneously, and generate a burr protruded from the distribution of this hole to the outside. Piling this metal sheet prepared with uneven part, integrate adjacent burr of concave apex of a lower layer with the burr of waist apex of an upper layer twisted each other, and charge radiation material through each hole of concave portion apex to the space between adjacent metal sheets. |
