Abstract
A sound absorbing component contains a fiber-reinforced thermoplastic resin expanded body having a percentage of void being not less than 50 vol %, and a resin molded body. An air layer is provided between the fiber-reinforced thermoplastic resin expanded body and the resin molded body. This sound absorbing component can effectively absorb the sound especially in the frequency region of 500 to 3000 Hz corresponding to the exterior noise problematic in automobiles, even if it is lightweight and thin.
