1. A method of manufacturing a battery electrode comprising:

a powder supply step of supplying a powder composed of granulated particles containing an electrode active material and a conductive aid;

a vibration step of breaking up particle aggregates in the powder by applying vibration to the powder;

a sorting step of passing the powder through at least one opening such that only particles having a predetermined particle diameter or less pass through the opening;

a moving step of moving the powder that has passed through the opening from an outlet position of the opening to a supply position; and

a deposition step of depositing the powder from the supply position onto a surface of a current collector in a layer having substantially uniform thickness.
