This sound-transmitting structure (100) comprises a sound-transmitting film (1) that permits the transmission of sound and obstructs the transmission of foreign objects, and a case (120) that has a sound-transmission opening (122). The sound-transmitting film (1) has a supporting material (12) being a non-woven fabric including an elastomer, and a resin porous film (11) layered upon the supporting material (12) and having polytetrafluoroethylene as the main component thereof. The sound-transmitting film (1) blocks the sound-transmission opening (122) by the supporting material (12) being welded to the case (120). |
