<P>PROBLEM TO BE SOLVED: To reduce both of material cost and manufacturing cost, and to obtain high heat insulation performance. Ž<P>SOLUTION: A plurality of air space forming sheet portions 2... are obtained by forming a synthetic resin sheet S like a strip of paper, or obtained in a shape like the strip of paper by sequentially folding the synthetic resin sheets S at predetermined spacings. When a heat insulating curtain with heat insulation is composed using the synthetic resin sheet S, plane regions 2pa... and 2qa... along long sides 2p... and 2q... on the sides of the long sides 2p... and 2q... of the plurality of air space forming sheet portions 2... are sequentially connected together in such a way as to join the planes on the same sides together. Also, the end side of a bonded joint 3 is joined to a surface of a sheet of base sheet 4 which is formed of the synthetic resin sheet S, so that a plurality of heat insulating air spaces 5... can be provided on the surface of the base sheet 4.
