    摘要: An electret condenser microphone includes: a substrate 13 in which an opening 25 is formed; an electret condenser 50 connected to one face of the substrate 13 so as to close the opening 25 and having an acoustic hole 12 and a cavity 2; a drive circuit element 15 connected to the one face of the substrate 13; and a case 17 mounted over the substrate 13 so as to cover the electret condenser 50 and the drive circuit element 15. Electric contact is established at a joint part between the electret condenser 50 and the substrate 13. The acoustic hole 12 communicates with an external space through the opening 25. The cavity 2 and an internal region of the case 17 serve as a back air chamber for the electret condenser 50.
