A condenser microphone, including at least one diaphragm, at least one electrode assigned to the diaphragm, comprising at least one ring-shaped insulator holding the electrode, comprising at least one diaphragm ring holding the diaphragm, and a holding ring holding the components mentioned. The mechanical and electrical properties of the condenser microphone are improved where the holding ring includes ceramic material. Preferably, the diaphragm ring and/or the ring-shaped insulator also consist(s) of ceramic material. With further preference, the ceramic material is zirconium oxide.
