PURPOSE:To facilitate mounting works, maintenance and the like by disposing a heat reserving and shape retaining body composed of solid mixture consisting of a solar heat absorbing and reserving constituent and organic high polymer. CONSTITUTION:A heat reserving and shape retaining body 2 whose heat reserving temperature is equal to or more than 0 deg.C is formed out of solid mixture consisting of a solar heat absorbing and reserving constituent and organic high polymer. The heat reserving temperature of the solid mixture is made to be 0 to 30 deg.C, so that a heat reserving constituent and organic high polymer are appropriately mixed so as to be formed. In this case, paraffin capable of absorbing solar heat or appropriate material can be used as a heat reserving constituent. As high polymer, appropriate material which can maintain its solid condition in a range of service temperature, can be used, and material exhibiting rubber like properties may be preferably used. The solid mixture is fabricated so that the heat reserving and shape retaining body 2 can be disposed in the back face of a mirror in a given shape such as a plate and the like. Finally, a blur preventive mirror comprises both the heat reserving and shape retaining body 2 and heat ray radiating material 3 as required disposed in the back face of the mirror 1. |
