Title: SILVER MIRROR, AND PRODUCTION METHOD AND EXAMINATION METHOD THEREFOR
Abstract:
Provided are: a silver mirror which is capable of maintaining, even under a high-temperature high-humidity environment, the high reflectance properties obtained by using silver, and which is capable of minimizing film stress and optical surface deformation; and a production method or the like therefor. The film stress after forming a reflective film is within the range of +100 MPa to -100 MPa. The film stress 24 hours after the reflective film has been introduced into a high-temperature dry environment having a temperature of 110˚C, and the film stress 24 hours after the reflective film has subsequently been introduced to a high-temperature high-humidity environment having a temperature of 85˚C and a relative humidity (RH) of 85% are within the range of +100 MPa to -100 MPa. The absolute value of the amount of change in the film stress value before and after subjection to these environments is not more than 40 MPa.
