A high reflection mirror has a layer structure comprising on a substrate, a TiOx layer, an Ag layer, an Al2O3 layer and a TiO2 layer in this order, or alternatively on a substrate, an SiOx layer, a Cr layer, an Ag layer, an Al2O3 layer and a TiO2 layer in this order (1<=x<=2). An SiOy protective layer may be formed on the top TiO2 layer (1<=y<=2). The high reflection mirror shows a high reflectance and a high durability and can be produced at a lower cost because of the reduced number of layers.
