摘要
A condenser microphone unit is provided that can flatten a frequency response in a high frequency band. The condenser microphone unit includes a unit case having an acoustic-wave entering hole, and a diaphragm accommodated in the unit case. The diaphragm is configured to vibrate in response to acoustic waves from the acoustic-wave entering hole. In the condenser microphone unit, an acoustic resistor is disposed between the acoustic-wave entering hole and the diaphragm. The acoustic resistor includes two elastic members in pressure contact with each other. At least one of the two elastic members is curved in a convex shape before contacting the other of the two elastic members by the pressure contact. A convex surface of one of the two elastic members is a surface that comes in pressure contact with the other elastic member.
