| 发明名称 | Electromechanical transducer and method of manufacturing the same | ||
| 摘要 | Disclosed is an electromechanical transducer, including: a cell including a substrate, a vibration film, and a supporting portion of the vibration film configured to support the vibration film so that a gap is formed between the substrate and the vibration film; and a lead wire that is placed on the substrate with an insulator interposed therebetween and extends to the cell, wherein the insulator has a thickness greater than the thickness of the supporting portion. The electromechanical transducer can reduce parasitic capacitance to prevent an increase in noise, a reduction in bandwidth, and a reduction in sensitivity. | ||
