Abstract: Provided are an electroacoustic conversion film web, an electroacoustic conversion film, and manufacturing methods thereof 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.
