A condenser microphone element is disclosed with an electrically conducting transducer membrane having an acoustically active area arranged to receive sound waves and to vibrate in response to the sound waves. The membrane is arranged in parallel with and at a distance from a back plate, which is formed from a non-conductive base. The base is provided with a conductive layer. The conductive layer has an active area that is arranged opposite the acoustically active area of the membrane and has a shape that faces the acoustically active area, and is delimited by an area where no conductive layer is provided. A microphone including the condenser element and a method of producing the microphone element are also provided.
