Zusammenfassung:	Distortions generated at ear portions of films at shorter sides of a resin film coated heat insulating/sound absorbing material can be eliminated. When the front and rear surfaces and both side surfaces in the direction of longer sides of the inorganic fiber mats are covered with band shaped resin films in a state that a predetermined spacing is provided between the mats, and the resin films are cut at a portion between the mats by a cutting blade along a direction of shorter sides in a state that the films are pressed by a pressing member 1, the resin films are pressed by a pressing member 1 having film setting portions 2 at both ends of its bottom surface, whereby the slopes 4 of the film setting portions 2 prevent the ear portions of the resin films at the cutting portion from spreading sideways.
