PROBLEM TO BE SOLVED: To improve separation strength with another laminated material by providing a surface of a barrier material of a heat insulating composite panel for a membrane type liquefied natural gas tank, with good adhesive property, and to provide the sheet-shaped barrier material having proper hardness and being easily handled in processing. SOLUTION: This sheet-shaped barrier material 1 integrated with a hard polyurethane foam molding as a heat insulating material for the membrane type tank for a ship transporting a liquefied natural gas, is obtained by superposing and integrating glass cloth 6 on one or both surfaces of aluminum foil 4 through adhesive layers 5a, and the glass cloth 4 is impregnated with adhesive to a degree not allowing the adhesive to leak up to the surface. As the fiber of glass cloth is exposed to the surface in a state of woven fabric, the adhesive intrudes into pores among the woven fabric of the glass cloth surface and fiber, when the other material is adhered and integrated, thus anchor effect is obtained, and adhesion force between the glass cloth and the other material can be improved.
