Abstract

This invention provides a fibrous sheet and its formed article having a light weight, a high strength, and an excellent acoustic characteristic. A fibrous material is mixed with thermally expandable pellets and formed into a sheet, which is then heated with the thickness of the sheet being controlled to thermally expand the pellets. A fibrous sheet having fibrous material around the thermally expanded pellets compressed to become high density is obtained. If desired, the fibrous sheet can be formed into predetermined shapes.
