  "textContent": "Provided is a silencing member for an electrified vehicle, which can suitably reduce a narrow band sound generated by a motor or the like, can handle a plurality of frequencies, can prevent generation of a wind noise, and can be miniaturized and thinned. The silencing member for an electrified vehicle includes a film type resonance structure which silences a sound generated from a sound source which is disposed in an electrified vehicle, in which the sound source generates a narrow band sound, the film type resonance structure is disposed in the same space as the sound source or in a vehicle cabin of the electrified vehicle, the film type resonance structure includes at least one film-like member, a frame which supports the film-like member to allow vibration thereof, and a back plate which is installed in the frame to face the film-like member, the film-like member, the frame, and the back plate form a back space surrounded by the film-like member, the frame, and the back plate, and the sound generated from the sound source is silenced by film vibration due to the film-like member of the film type resonance structure.",
