PROBLEM TO BE SOLVED: To enable highly-reliable light resistance evaluation by reproducing accurately in a short period ultraviolet deterioration of a polymer material such as an interior material exposed to sunlight transmitted through a window glass. SOLUTION: Each of various glass face materials 3 supposed as the window glass is provided between an artificial light source 1 in a light resistance testing machine and a sample installation part 2, and a plurality of samples 4, 4, etc. installed on the sample installation part 2 are irradiated with light from the artificial light source 1 transmitted through the glass face material 3.
