An electret condenser microphone includes a casing member, a circuit board
disposed in the casing member, an electrically insulating member disposed
on the circuit board and having an outer surface opposing and spaced
apart from the casing member, and an inner surface defining a central
opening, an electrode plate mounted on the electrically insulating
member, a plurality of electrically connecting members each intervening
between the circuit board and the electrode plate to have the circuit
board and the electrode plate electrically connected with each other,
each of the electrically connecting members having a first portion
disposed along the inner surface of the electrically insulating member, a
second portion integrally formed with the first portion and radially
outwardly extending from one end of the first portion, and a third
portion integrally formed with the first portion and radially outwardly
extending from the other end of the first portion, and a diaphragm
disposed along the electrode plate and spaced apart from the electrode
plate at a predetermined space distance.
