<p>Provided is a method for producing a vibrating membrane unit (1) used for a microphone, the vibrating membrane unit being provided with: a tubular support member (11) made of resin, which opens in at least one side in an axial direction thereof; and a vibrating membrane (21) fixed to an opening peripheral portion of a first end face (12) in such a manner as to cover an opening of the first end face (12), the first end face (12) being an end face of the tubular support member (11) in the above one side thereof in the axial direction thereof. The method comprises: a fixing step in which the vibrating membrane (21) is brought into a state fixed to the opening peripheral portion of the first end face (12) of the tubular support member (11); and a tension providing step in which, after the foregoing fixing step, a predetermined tension is provided to the vibrating membrane (21) by utilizing radially outward deformation of the tubular support member (11).</p> |
