Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a heat insulation bag body, which effectively maintains the moisture absorbing and desorbing function of a cellulose fiber heat insulator so as to prevent additives such as a flame retarder from scattering and allow for a uniform insulation effect and a soundproof effect resulting from a suppressed sedimentation phenomenon with age, and to provide a manufacturing method and apparatus of the heat insulation bag body.SOLUTION: A heat insulation bag body formed of an air permeable composite material of a porous thermoplastic resin film having air permeable micro pores of which a single side is laminated with a nonwoven fabric or other fabric body is filled with a cellulose fiber heat insulator. The bag body of claim 1 may be filled with the cellulose fiber heat insulator compacted into a shape corresponding to the bag body, with an opening to be heat sealed.
