PROBLEM TO BE SOLVED: To produce a low density and light weight heat insulation material having a high constructible property and heat insulating property, and a good repulsive force against compression and vibration durability. SOLUTION: This device for producing the low density laminated heat insulation material is to produce a low density laminated heat insulation material 7 by laminating a fibrous sheet 1 constituted mainly by carbonaceous fibers in multiple layers while spraying a binder on both surfaces of the fibrous sheet and folding the fibrous sheet 1 in lateral direction. The production device is constituted by a swing mechanism for supplying the fibrous sheet 1 spun from a carding means on a loading stand capable of lifting up and down or a conveyer 6 capable of advancing, and a spraying mechanism for applying the binder on the fibrous sheet. The swing mechanism can swing in the thickness direction of the fibrous sheet 1, and the spraying mechanism is mounted at the lower part of the swing mechanism and can move back and forth in the width direction of the fibrous sheet.
