SILVER REFLECTION FILM, LIGHT REFLECTION MEMBER, AND MANUFACTURING METHOD FOR LIGHT REFLECTION MEMBER

摘要

[Problem] To provide at low cost and good producibility a silver reflection film, which has a high reflectance, the reflectance of which does not change easily even before and after heating, and which does not soften easily, and a light reflection member using same; and to provide a light reflection member having a silver-plated reflection film of good heat resistance and a conductive base material using a plating method. [Solution] A silver reflection film obtained from silver or a silver alloy, wherein the surface of the silver reflection film has 50% or more of regions in which (100) faces of crystals of the silver reflection film are oriented in the direction normal to the reflecting surface of the silver reflection film and there are regions in which (221) faces of crystals of the silver reflection film are oriented in the direction normal to the reflection surface of the silver reflection film; a light reflection member obtained from said silver reflection film and a conductive base material; and a manufacturing method therefor.
