A contact structure of a film speaker is provided to generate the sufficient volume by transmitting a signal current to whole area of film while maintaining the durability to the vibration of film. A film speaker comprises a piezoelectric film unit(2), a piezoelectric film(3), a terminal unit(6) and a metal conductive layer(12). The piezoelectric film unit(2) is made by coating a conductive polymer layer(4). The terminal unit(6) is connected to the piezoelectric film unit(2) electrically. The metal conductive layer(12) is coated along the circumference of the piezoelectric film unit(2) and has the higher conductivity than the conductive polymer layer(4) relatively. The terminal unit(6) is formed to stick to the metal conductive layer(12). |
