PROBLEM TO BE SOLVED: To provide a heat insulation sheet excellent in heat insulating properties, which is lightweight and flexible, and in which a holding and winding are possible. SOLUTION: A laminate solving a problem of dusting which is a defect of aerogel is provided, noting that the aerogel is lightweight and can exert excellent insulating characteristics. The laminate comprises a resin coat or an inorganic fiber cloth 2 resin-impregnated arranged on one surface of an aerogel sheet 1 in which a porosity is 80 vol.% or more, and a reinforcing sheet 3 having a heat resistance of a heatproof temperature or more of the aerogel sheet 1 on the other surface of the aerogel sheet 1. The laminate is laminated and integrated by a mechanical coupling means. The mechanical coupling means has an engaging part on both surfaces of the laminate, and is to be preferably a fastening member 4 having a penetration part penetrating the laminate, more preferably a rivet.
