Abstract: A method of manufacturing a formed body for an electrode includes: preparing an electrode material; placing a shape retaining member having an rectangular tubular shape with one opening portion L thereof facing down, and supplying the electrode material into the shape retaining member from the other opening portion M thereof; and discharging the electrode material onto a support from the opening portion L while relatively moving the opening portion L and the support, to form a film, a bulk density D1 of the electrode material in the first step and a bulk density D2 of the electrode material at the opening portion L satisfying a relationship of D2/D1=1.1 to 30, and a width T1 of the opening portion L in a short side direction and a distance T2 between the end portion X of the opening portion L and the support satisfying a relationship of width T1>distance T2.

Abstract: A method of manufacturing a formed body for an electrode includes a first step of dropping an electrode material containing an electrode active material into a gap between a pair of transport belts and introducing the electrode material between transport surfaces of the pair of transport belts; a second step of belt-transporting and pressurizing the introduced electrode material with the pair of transport belts; and a third step of transferring the electrode material after the belt transporting and the pressurization, on a deposition belt, in which a transport direction in a transport, passage through which the electrode material is transported, of the deposition belt intersects a transport direction in a transport passage, through which the electrode material is transported, of the pair of transport belts.
