PROBLEM TO BE SOLVED: To provide a reflection mirror for a heliostat having an improved durability as compared to the conventional reflection mirror for a heliostat.SOLUTION: A reflection mirror 10 for a heliostat includes: a reflection mirror 18 with a protective layer which has a reflection layer 14 formed on substantially the whole surface on a back surface of a transparent substrate 12 and has a protective layer 16 formed on substantially the whole surface on the reflection layer 14; and a protective plate 22 having non-gas permeability and non-water permeability which overlaps substantially the whole surface of the back surface of the reflection mirror 18 with the protective layer and is adhered to substantially the whole surface of the back surface of the reflection mirror 18 with the protective layer with an adhesive 20. The reflection mirror 18 with the protective layer, for example, can be configured with an ordinary silver mirror offered commercially. |
