PROBLEM TO BE SOLVED: To provide a heat shielding material which is applicable to a heat insulating structure at locations between wooden members such as roof rafters and wall vertical frames of a house, does not store heat therein even if thermal load is applied thereto from the outside, and facilitates mounting thereof from the interior of a room. SOLUTION: The heat shielding material 1 is formed of an upper layer 1A, an intermediate layer 1B, a bottom layer 1C, and air layer spaces S1, S2 between the respective layers. Each layer has a radiant heat reflective layer Re arranged on an upper surface thereof. The upper layer 1A is formed of a shape retaining upper sheet 12, and has bent leg portions 12L, 12R which have stability and are arranged on both sides of the sheet 12 via respective bent portions 12S. Then the heat shielding material 1 is fitted and installed in a gap between the wooden members such as the rafters 3, and the bent leg portions 12L, 12R strain themselves to bear both surfaces of the wooden members by virtue of their stability F0, whereby the heat shielding material 1 is held in an appropriate position.
