LIGHT REFLECTING MIRROR, METHOD FOR MANUFACTURING SUCH LIGHT REFLECTING MIRROR AND PROJECTOR

摘要

A light reflecting mirror, which can be easily manufactured by using a light-weight and low-cost plastic base material and has a high reflectance, and a method for manufacturing such light reflecting mirror. In the light reflecting mirror, a reflecting film (52) containing silver is formed on a surface of the plastic base material (50) whose thermal deformation temperature is 130°C or higher. The plastic base material (50) is a thermosetting resin molding, the surface of the reflecting film is a smooth plane having a PV (peak to valley) value of 0.5Vm or less without a sharp angle protrusion, and further, the reflectance of the reflecting film surface is 96% or more.
