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.

Abstract: Provided are an electroacoustic conversion film web, an electroacoustic conversion film, and a method of manufacturing an electroacoustic conversion film web in which costs can be reduced by reducing the number of operations without damage to thin film electrodes, the points of electrode lead-out portions can be freely determined, and thus high productivity can be achieved. A preparation step of preparing an electrode laminated body in which a single thin film electrode and a single protective layer are laminated and a lamination step of laminating the electrode laminated body and an piezoelectric layer are included. A non-adhered portion that is not adhered to the piezoelectric layer is provided in at least one end portion of the thin film electrode in a case where the electrode laminated body and the piezoelectric layer are laminated in the lamination step.
