Zusammenfassung: | PROBLEM TO BE SOLVED: To achieve a film structure that entirely satisfies humidity resistance, heat resistance and light resistance such that mechanical deterioration and functional deterioration of a film can be suppressed even in a harsh usage environment.SOLUTION: A reflection mirror is configured such that an adhesion layer 2, a reflection layer 3 made of an aluminum film and a dielectric layer 4 are stacked in this order on a resin substrate 1. The adhesion layer 2 is composed of three layers, and is configured such that a first layer 2a, a second layer 2b and a third layer 2c are stacked in this order from the side of the resin substrate 1. The first layer 2a is composed of a cerium oxide film, and the second layer 2b is composed of an aluminum oxide film. |
