In addition, provided is an apparatus for manufacturing an electrode body, which includes the above-mentioned powder supply device and can efficiently manufacture an electrode body. A powder supply device (1) includes a rotor (7) which makes powder (10) fall into a discharge opening (6c), and a mesh body (8) which covers the lower end of the discharge opening (6c). Grooves (7b) are formed on an outer circumferential surface (7a) of the rotor (7) parallel to the axial direction of the rotor (7) and at equal intervals in the circumferential direction. The rotor (7) is rotatably supported in a storing portion (6a) so that the axis of the rotor (7) is parallel to the width direction of the discharge opening (6c) as viewed in a plan view and is arranged horizontally. The gap which constitutes the conveyance passage for the powder (10) is formed between the outer circumferential surface (7a) and the inner surface of the storing portion (6a) so that they are spaced apart from each other by a distance (d1). The mesh body (8) is arranged away from the outer circumferential surface (7a) of the rotor (7) by the distance (d2).
