Abstract: A method of manufacturing a lithium-ion secondary battery electrode sheet disclosed herein includes the step of preparing powder 220 of granulated particles. In this step, the powder (220) of granulated particles (240) including active material particles (241) and a hinder (242) is prepared. The powder (220) is deposited on a strip-shaped collector foil (201) that is being conveyed. Then, the powder (220) is removed from widthwise center portions (202) and (203) of the collector foil (201), and a squeegee (106) is brought into contact with the powder (220) remaining on the opposite sides of the center portions (202) and (203) of the collector foil (201), thus adjusting the thickness of the powder (220). Subsequently, the powder (220) remaining on the opposite sides of the center portions (202) and (203) of the collector foil (201) is pressed.
