A sound proof material here disclosed comprises an exterior material layer 8 including a holding material 3 made of a woven fabric and a skin material 2 made of a thermoplastic resin film, and a sound absorbing material layer 9, the exterior material layer 8 being laminated on the sound absorbing material layer 9 so that the skin material 2 is located on the surface side of the sound proof material, whereby the sound proof material can endure long-time use without deterioration in moldability under inhibition of aging in severe operating environments so that the sound proof material can be suitably used while suppressing sound from a sound source around an engine installed in an engine compartment of an automobile.
