Abstract
A heat insulating/sound absorbing material wherein the entire surface of an inorganic fiber mat is covered with a synthetic resin film or films and a method of producing the same. Front and rear surfaces of an inorganic fiber mat as well as both side surfaces along a longer side thereof are covered with synthetic resin films ; both ends of the synthetic resin films in the direction of a longer side of the inorganic fiber mat are extended from both ends in the direction of a shorter side thereof to thereby cover both end surfaces in the direction of a shorter side of the inorganic fiber mat ; an adhesive is applied continuously or discontinuously along the direction of a longer side of film to a portion in the direction of a shorter side of the inorganic fiber mat whereby the inorganic fiber mat and the synthetic resin films, and a mutually opposing portion of the synthetic resin films are bonded so as to make air communicate through unbonded portions.
