Abstract
Provided is a powder supply device for a secondary battery which can always supply a fixed amount of powder with high accuracy without being influenced by a state of the powder. In addition, provided is an apparatus for manufacturing an electrode body, which includes the powder supply device and can efficiently manufacture an electrode body. The powder supply device includes a rotor which makes powder fall into an opening, and a mesh body which covers the lower end of the opening. Uneven portions or projecting portions are formed on the outer circumferential surface of the rotor. The rotor is rotatably supported in a storing portion. The gap is formed between the outer circumferential surface of the rotor and the inner surface of the storing portion so that they are spaced apart. The mesh body is arranged away from the outer circumferential surface of the rotor.
