A film speaker using a corona method is provided to realize uniform sound output by forming uniform thickness of a polymer conductor film on the surface of a piezoelectric film. A film speaker using a corona method includes a piezoelectric film(200), a polymer conductor film(202), an electrode(204), and a terminal(206). The piezoelectric film has a predetermined shape and is surface-treated by using the corona method. The polymer conductor film is applied to both sides of the piezoelectric film and supplies the piezoelectric film with power. The electrode is formed to be elongated along an edge of the polymer conductor film. The terminal is extended outside the polymer conductor film from the electrode. |
