Beschreibung
Zusammenfassung:	PROBLEM TO BE SOLVED: To obtain a heat insulating material having a lightweight, excellent heat insulating properties, sound absorbing qualities, etc., excellent workability in use and improved mechanical strength such as flexural strength, impact strength, etc., and to provide a method for readily producing the heat insulating material. SOLUTION: This heat insulating material is characterized in a fiber assembly comprising a staple fiber comprises at least two or more kinds of staple fiber assemblies, the staple fiber assemblies are composed of matrix fibers and low- melting fibers containing components having melting points lower than those of the matrix fibers and at least one kind of the matrix fibers is a hollow type structure.
