An electret condenser microphone with a low noise figure and a method for producing the same are disclosed. An electret variable condenser is first installed into a housing, and then an ASIC amplifier and a printed circuit board are installed into the housing. The ASIC amplifier is electrically connected to the electret variable condenser. It reduces the noise figure effectively and ensures the normal transmission of the effective sound. In particular, it ensures the stability and reliability of the ASIC amplifier during use. The process is simple, the production efficiency is high, and the processing cost is low.
