PROBLEM TO BE SOLVED: To provide a superior electroacoustic transducer diaphragm which improves the mold releasability, the productivity and the quality of the diaphragm.;SOLUTION: The diaphragm is made by laying a surface layer on a PEN film of 3 μm or thicker and 25 μm or thinner containing ethylene-2,6-naphthalate resin and/or ethylene-2,7-naphthalate resin as a main component, thereby providing a surface resistance value of 1013 ohm/square or less.;COPYRIGHT: (C)2006,JPO&NCIPI
