There is provided a heat shielding member for a thermal insulation structure which does not form a heat accumulator even if it receives a heating load from the outside and which is easily fixed and installed from the indoor side when it is applied to the thermal insulation structure between timbers such as rafters, vertical frames of a wall and the like of a house. The heat shielding member is structured such that spaces of the air layer are formed between an upper layer, an intermediate layer, and a lower layer, a radiant heat reflective layer Re is provided on upper faces of respective layers, and the upper layer is formed of a shape-retention upper sheet to which a cover sheet is laminated, wherein bent-up legs having restorability are disposed on both sides of the shape-retention upper sheet through the intermediary of bent-up parts, and the heat shielding member is engaged and mounted between timbers such as rafters having an interval therebetween, and it is held in a proper posture when the bent-up legs are stretched against and held by faces of the timbers, so that the interval is closed by the cover sheet, thereby restraining radiant heat from transferring downward from the upper layer, and blocking heat permeated the upper layer by the intermediate layer and the lower layer, discharging heat through spaces, and restraining the heat from transferring from the outdoor side toward the indoor side without accumulating heat.
