Abstract:
The sound-transmitting structure (100) of the present invention includes a sound-transmitting membrane (1) that allows passage of sounds and prevents passage of foreign matters and a case (120) having a sound-transmitting opening (122). This sound-transmitting membrane (1) includes a supporting member (12) that is a nonwoven fabric containing an elastomer and a porous resin membrane (11) disposed on the supporting member (12) and containing polytetrafluoroethylene as a main component. The sound-transmitting membrane (1) covers the sound-transmitting opening (122) with the supporting member (12) welded to the case (120).
